Because today, as I said, is day 1888. We were reading paragraphs 1373 to 1377. We were talking about the real presence of Jesus Christ in the Eucharist, which is remarkable, not only for its own sake, but also because, you know, I didn't read ahead yesterday, but I was talking about transubstantiation yesterday. And so gave you a little sneak pink, little heads up into what we're going to read today. It is a miracle that's akin, I don't know, I was going to say akin to the incarnation. But it really is that at every mass, in every tabernacle around the world, bread and wine become truly, really and substantially, the body and blood, soul and divinity of our Lord Jesus Christ.

It's incredible. And so as we talk about this holy thing, I mean, a little joke at the beginning, but as we talk about this holy thing, let's just ask the Lord to help us to appreciate even to begin to appreciate the depth of his love for us that at every mass, he transforms bread and wine into his body and blood, truly, really, and substantially. So let's pray now. Father in heaven, we give you praise, and we thank you. We thank you for the gift of your church, the gift of faith, hope and love. We thank you for the gift of your Holy Spirit. We thank you for the gift of your son, for you so loved the world that you.

you gave your only son so that everyone who believes in him may not perish but might have eternal life. And you've given us your son to be our food in this miraculous, mysterious, incredible way. Help us to recognize him in the breaking of the bread. Help us to really truly see who Jesus is as he comes to us on a regular basis, daily basis in the Eucharist. And help us to fall in love with him as you are in love with us. In Jesus' name we pray. Amen. In the name of the Father and of the Son and of the Holy Spirit. Amen. It is day 188. We're reading paragraphs 1373 to 1377. The presence of Christ by the power of His Word and the Holy Spirit. Christ Jesus, who died, yes, who was raised from the dead, who is at the right hand of God, who indeed intercedes for us,

is present in many ways to his church. In his word, in his church's prayer, where two or three are gathered in my name, in the poor, the sick, and the imprisoned, in the sacraments of which He He is the author, in the sacrifice of the Mass and in the person of the minister. But he is present most especially in the Eucharistic species. The mode of Christ's presence under the Eucharistic species is unique. It raises the Eucharist above all the sacraments as the perfection of the spiritual life and the end to which all the sacraments tend. In the Most Blessed Sacrament of the Eucharist, the body and blood, together with the soul and

divinity of our Lord Jesus Christ, and therefore the whole, whole Christ is truly, really, and substantially contained. This presence is called real, by which is not intended to exclude the other types of presence as if they could not be real, too, but because it is presence in the fullest sense. That is to say, it is a substantial presence by which Christ, God, and man, makes himself wholly and entirely present. It is by the conversion of the bread and wine into Christ's body and blood that Christ becomes present in this sacrament. The Church fathers strongly affirmed the faith of the Church in the efficacy of the Word of Christ and the action of the Holy Spirit to bring about this conversion. Thus St. John Christostom declares,

It is not man that causes the things offered to become the body and blood of Christ, but He who was crucified for us, Christ himself. The priest, in the role of Christ, pronounces these words, but their power and grace are gods. This is my body, he says. This word transformed the things offered. And St. Ambrose says about this conversion, Be convinced that this is not what nature has formed, but what the blessing has consecrated. The power of the blessing prevails over that of nature, because by the blessing, nature itself is changed. Could not Christ's word, which can make from nothing what did not exist, change existing things into what they were not before? It is no less a feat to give things

their original nature than to change their nature. The Council of Trent summarizes the Catholic faith by declaring, because Christ our Redeemer said it was truly his body that he was offering under the species of bread, it has always been the conviction of the Church of God, and this Holy Council now declares again that by the consecration of the bread and wine, there takes place a change of the whole substance of the bread into the substance of the body of Christ our Lord, and of the whole substance of wine into the substance of his blood. This change, the Holy Catholic Church has fittingly and properly called transubstantiation. The Eucharistic presence of Christ begins at the moment of the consecration and endures as long as the Eucharistic species subsist.

Christ is present whole and entire in each of the species and whole and entire in each of their parts in such a way that the breaking of the bread does not divide Christ. All right, there we have it, paragraphs 1373 to 13. 1377 short paragraphs, right? I think another six, five paragraphs here, and yet so powerful, just incredible. Let's highlight. Let's just kind of go in order here because if we don't, I'm going to get lost. I'm going to talk about everything that I want to begin to be able to talk about everything that I love about Jesus and the Eucharist, about how good God is for us. And so paragraph 1373 kicks off by saying that, okay, Jesus Christ is truly present in many ways.

and he lists the sum of the ways, right? Christ is present to us in His Word, right? When we hear the scriptures proclaimed and his church's prayer, when two or three are gathered in his name. Christ is present in the poor, the sick and the imprisoned, in the sacraments of which he is the author, essentially all of the sacraments. Christ is present in the sacrifice of the Mass

and in the person of the minister, right, in the person of that priest, the bishop. But he is present most especially in the Eucharistic species, that it is a unique presence. And I just, this is beautiful. You know, always, always I'll talk about the Eucharist as being the true body, blood, soul, and divinity of Jesus. Where do you get that kind of language? Well, one of the places we get that kind of language is from the Council of Trent originally,

and here expressed to us in paragraph 1374, where it says, in the most blessed sacrament of the Eucharist, the body and blood together with the soul and divinity of our Lord Jesus Christ. And therefore, the whole Christ is truly, really, and substantially contained. Now, this present is called real, because all the other presences are real as well, but this is presence in the fullest sense. That is to say, it's a substantial presence by which Christ, God and man, makes himself holy and entirely present. This is something so beyond our imaginations. It's beyond our understanding that Jesus Christ, body, blood, soul, and divinity, is truly present in the Eucharist. Now, these words are important for us, truly, really, and substantially contained, that he's present in truly, really, really.

and substantially. Sometimes we will talk about Christ's physical presence. And that is not, it's not wrong to talk about Christ's physical presence because here's the Eucharist. That is physically there, right? We receive the Eucharist. We adore the Eucharist. We get to consume the Eucharist. There is, he says take and eat, take and drink. Those are physical actions. In fact, in John chapter 6, when Jesus uses the term for flesh, his own flesh, at one point he actually uses the term sarks, right? Talking about like a physical presence. That truly is me. That's my body and blood, soul, and divinity. Okay. At the same time, a more precise language, I think, a more precise language that doesn't lead

to it being mistaken. It doesn't lead to some mistakes is that Christ is, the whole Christ is truly, really, and substantially contained. Because we recognize that this is not cannibalism, right? We're not eating the physical flesh of Jesus, but it truly is, really is, and substantially is the body, blood, soul, and divinity of Jesus. And that's kind of a key distinction that we would like to maybe like to make here. Now, moving past that because that's a distraction.

I mean, I think in some ways it's a distraction to get away from the fact that Jesus, the whole Christ, right? Body, blood, soul divinity is truly, really and substantially contained. That's the heart of this. Now, going on, we recognize that when is it that Christians are to believing this? Well, from the beginning, we know that in John chapter 6, when Jesus made it clear that he was going to give us his flesh and blood as food and drink that many disciples said this saying is hard who can accept it and they walked away. In John chapter 6 verse 66, many of his disciples returned to

their former way of life and no longer accompanied it from the beginning. From the beginning, it was clear, well, not clear in the sense that we understand how he's doing this or what's really happening. But it was clear that there's something unique about the Eucharist, something that is so challenging to us that that was recognized, that was recognized from the beginning. but we also have the church fathers. Now, we're looking at St. John Christostom and St. Ambrose, and there are a couple of centuries into Christianity. But if you want to go all the way back, you can go all the way back to St. Ignatius of Antioch

in year 107 talking about that Jesus Christ, the Eucharist, truly is, is the true flesh and blood of Jesus Christ, our Savior. But here we have St. John Christostom. He talks about this. And he says, it is not man that causes the things offered to become the body and blood of Christ, but he who is crucified for us. Christ himself does this. Yes, the priest.

And the role of Christ pronounces these words. but their power and grace are gods. This is my body, he says, and this word transforms the things offered. Remember, this is placed under the office of the priesthood. And we mentioned the other day that there are people who can come to the conclusion that, yes, Jesus was very serious when he said in John 6th, that my flesh is true food, my blood is true drink. Jesus was being literal when he said at the last supper, this is my body, this is my blood.

And they can still miss out on the heart of the Eucharist, not the heart of the Eucharist. They can still miss out on partaking. participating in the Eucharist because they don't have the priesthood. When we've abandoned the apostolic succession, when we've abandoned priesthood, then we no longer have the ability to confect the Eucharist because even from the beginning, here is St. John Christostom writing in the first couple centuries. And he's saying that it's the priest in the role of Christ who pronounces these words and that power and grace come from God.

And so there's a connection and an intrinsic connection between the reality of Christ's presence in the Eucharist and the ministry, the role, the action of the priest. Now, going on, St. Ambrose, Ken talks about this. And this is one of those situations where I always like to, not make a joke, but kind of like show how to demonstrate or at at least point out how strange it is that we would say the same God who can, who made everything out of nothing, that he can, yes, he can make one thing into another. Right. If you were to say, I don't know how God could possibly do this. Well, okay, what we remember, we remember, right, from the beginning that in the beginning, God just said let there be light and all of a sudden there

was light, that the God who can create everything out of nothing with a word, that he can't transform one thing to another. Here's what St. Ambrose says, it is no less a feat to give things their original nature than to change their nature. Could not Christ's word, which can make from nothing what did not exist, change existing things into what they were not before? And so we recognize that, yes, this is true. And then in the last two paragraphs here, because this is just, man, in 1376, it highlights what is actually happening. And it's the fancy word that I mentioned. the other day, the word transubstantiation, right? That here's the accidents that remain the same, but the substance changes. And this is, the accidents are what the appearance is, what the look,

the vision, the smell, taste, sound, all of those things that touch, those accidental properties, those remain the same, but the substance of the thing, the what it isness of the thing, changes. And it doesn't share it the thing. So there are some Christians would say const substantiation in the sense that, okay, so it is both, bread and wine and the body and blood of Christ. And the church has been definitive of this in saying this. Church has said that it's the whole substance of bread and wine has become the whole substance of Christ's body and blood. And so that changed calling transubstantiation. It's fittingly, properly called transubstantiation. Now, this is so full, this transformation, this, sorry,

that transformation, because the form doesn't change, but the substance does. Transubstantiation is so profound that he says this, the Eucharistic presence of Jesus Christ begins at the moment of the consecration and endures as long as the Eucharistic species exists. So what's that mean? Well, that means as long as the bread is recognizable as bread, as long as the, what's in the cup, right, the chalice of Christ's blood is recognizable as wine that remains the body of Christ and the blood of Christ. So as long as the Eucharistic species exist, it still is the body of blood of Christ's, but once digestion happens, that ceases to be under the appearance of bread and wine, therefore it ceases to be the body and blood of Christ. That makes sense. And so, you know,

one of the things that can happen at times is sometimes people will maybe drop a consecrated host. They'll drop the body of Christ and into the dirt or something. And so what do you do there? Well, a person could consume it, right? A person could consume the Eucharist in that case. But there are times when that wouldn't be proper. And so what someone will do is they'll take that host, that consecrated host very carefully and place it in some kind of water and place that water in a very safe place until the water dissolves the consecrated host. So it's no longer recognizable as bread, in which case it's no longer actually the presence of Jesus Christ, if that makes any sense. So if that ever happens. And the same thing happens when it comes to,

so we have like linens, right? The purificator is that white cloth that we use to wipe the rim of the chalice when we receive the precious blood. So there are typically stains of the precious blood on that white cloth. And so in order to clean them, there is a procedure to clean them. Basically, they get soaked in water for over 24 hours so that what appears to be wine breaks down. It's no longer no longer wine. And then that gets poured into a holy place.

And then the linens are washed like a normal way. That's one of the ways in which we recognize it. And that Jesus Christ is truly present as long as the eucryx species subsists. The last little note I just want to offer to everyone is it says Christ is present whole and entire in each of the species and whole and entire in each of their parts. What's that mean? That means that if you went to Mass and you receive simply the body of Christ, that's the whole Christ. You don't get more, quote, unquote, more Jesus if you receive the body and the blood.

In a similar way, maybe you've been in this case before where you've gone to Mass and maybe they didn't plan it out very well and they ran out of hosts. And so the priest or the extraordinary ministers of Holy Communion began like fracturing the host into smaller pieces. And maybe I remember this as a kid saying, oh, I only got a little piece. We would say this. You know, the church would say, be assured that Christ is present whole and entire in each of the species in the body and or the blood and whole and entire in each of their parts. So if you only had a small sip of Jesus versus a large, I guess for lack of a better term, gulp of the precious blood, you'd receive the full. Christ. If you only had a crumb, you know, a small piece of the host, or the whole, you know,

the big priests, you know, presider's host, you would still receive the whole Christ regardless. So it's not like Christ is being divided. He's not being divided. It's the whole Christ. And this is one of the things that just like keeps coming back to the reality of just, it is one thing to talk about God. It's another thing to pray to God, right? It's another thing, one thing to just ruminate and learn data about who God is, it's another thing to be in relationship with this God. And similarly right now, it's one thing to say, Jesus Christ is truly present in the Eucharist. It's amazing and it is amazing. It's another thing to go and visit him. It's another thing to go to mass. It's another thing. We're going to talk about this tomorrow when it comes to adoration,

when it comes to the worship of Jesus Christ in the Eucharist, and the visiting of the tabernat. where the presence of Christ abides. We'll talk about that tomorrow, but just stoke your hearts. Stoke your hearts, that sense of like, why not today, if you can, stop by a church and recognize when you see that candle burning, you realize, hey, this is Jesus Christ truly present waiting for me. We'll talk about that more tomorrow, but just right now, get your hearts, get the love of your hearts, get the fire of your hearts stoked so that you and I can both say, okay, I don't just want to hear about Jesus. I want to, I want to see him. I don't just want to hear about how great it is to have a relationship with the God who makes himself present to us. I want to have that relationship.

I want to live in that relationship. I don't just want to talk about how amazing it is that the presence of Christ abides in this unique way in the Eucharist. I want to visit him. And maybe I want to visit him today. And if you can't, just let your heart reach out through space to that tabernacle. You say, Jesus, let me abide in you. One of the Psalms says, Lord, to dwell in the doorway of your temple is better than a thousand days anywhere else. One day, one day in the outskirts of the temple is better than a thousand elsewhere. And the same thing is true, even more, maybe even more true. Just like, let me just, even just walk by the Catholic Church and know that that that built church building is like a giant tabernacle around the small tabernacle in which is the body blood,

soul and divinity of our Lord and Savior Jesus Christ. Amazing. I'm praying for you. Please pray for me. My name is Father Mike. I cannot wait to see you tomorrow. God bless.
