EVERY BAPTIZED CATHOLIC IS A PRIEST. Homily for Twenty-Second Sunday
Ps 63/Rm 12:1-2
For today’s homily, I would like to do a little lectio divina—a sacred reading of the very short Second Reading from Romans. It’s only two verses, but there is a lot there to reflect on.
“I urge you, by the mercies of God, to offer your bodies as a living sacrifice, holy and pleasing to God” (Rm 12:1).
Let’s begin with a show of hands. Raise your hand if you are a priest. Raise your hand if you are baptized. All of you with your hands up, you should have raised them the first time. Every baptized man and woman is a priest, not in the same way that I am, but priests nonetheless. The Catechism of the Catholic Church, in describing the different graces or effects of the Sacrament of Baptism, states “the person baptized is incorporated into the Church, the Body of Christ, and made a sharer in the priesthood of Christ” (CCC 1279). The Second Vatican Council’s Dogmatic Constitution on the Church, Lumen Gentium, teaches that there are two ways of sharing in the one priesthood of Jesus Christ. They are the common priesthood of all the faithful and the ministerial (ordained) priesthood. This reality of all the baptized sharing in the Priesthood of Christ comes from the first Pope, St. Peter. “…like living stones be yourselves built into a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ” (1 Pt 2:4-5). He is saying basically the same thing that St. Paul was saying to the Romans, “offer your bodies as a living sacrifice, holy and pleasing to God, your spiritual worship”. From time immemorial, what has been the chief function of priests? To offer sacrifice.
In the middle of the celebration of the Mass, immediately after the gifts of bread and wine are placed on the altar, and the ordained priest has washed his hands, he turns to the common priests and instructs them Orate fratres, “Pray brethren that my sacrifice and yours may be acceptable to God the Almighty Father”. My sacrifice and yours. Why not just say “our” sacrifice? Because we share in the Priesthood in two different ways and so our manner of offering sacrifice is different. Also, the sacrifice itself is different. The ordained priest is standing in persona Christi and is about to offer the sacrifice of Christ. It is Christ the High Priest, through the hands of the ordained priest, offering Himself. The one and the same sacrifice that He made on Calvary as priest and victim is offered on every altar in every Catholic Mass from the time of the apostles until Christ comes again. And Christ is ALIVE. He is crucified AND risen. It is not a co**se that is offered, but the living, breathing God in the flesh. In the third Eucharistic Prayer, immediately after the consecration and the Mystery of Faith, the ordained priest prays to God the Father that “we offer you in thanksgiving this holy and LIVING sacrifice”.
So, the ordained priest offers the sacrifice of Christ to the Father. The baptized lay priests offer the sacrifice of themselves. You cannot offer what is outside of you. You cannot offer to God what is not yours to give. Joseph Ratzinger wrote, “the only real gift man should give to God is himself”. Thus, St. Paul urges Christians to offer themselves to God as a living sacrifice.
Paul starts with the body. Human beings are creatures of body and soul. The body is not bad in itself. There is a common misconception that Catholicism sees the body as bad. This is not true. If the body were bad, why should we be offering it to God? Pope St. John Paul II did a multi-year catechesis in the early 1980s on the beauty and goodness of the human body as created by God. This became known as the “Theology of the Body”. So, the body is good, but it can be corrupted by sin.
There are three deadly sins that directly involved the body. Gluttony, Lust, and Sloth. They all occur when we misuse (or even abuse) the body God gave us, the body that St. Paul calls a temple of the Holy Spirit. The misusing of the body is a sin, not because the body is not good, but because it is. When committing these sins, we’re not treating the body as good.
The psalmist sings of the thirsting of the soul for God, but the body of course thirsts as well. The two are not mutually exclusive. The body thirsts for sustenance in the form of food and drink, without which it cannot live. It thirsts for s*x, without which the species dies. The body thirsts for pleasure and rest to keep it from falling apart. It’s when we misuse these as ends in themselves instead of as true nourishment as God intended that we sin, and instead of nurturing the body, we slowly kill it. For instance, the drunk who quenches his thirst not with good ole H2O but with liquor, slowly kills his liver. “…offer your bodies as a living sacrifice, holy and pleasing to God”. An early Church Father wrote, “…for bodies subject to sin are considered not to be alive but dead, since they have no hope of obtaining the promise of eternal life”.
Now we move on to the second verse. “Do not conform yourselves to this age but be transformed by the renewal of your mind”. “…of your mind”. If the body is to be a living sacrifice, it does not happen apart from the soul. We human beings are rational creatures with rational souls. The animal sacrifices of the Old Covenant were not only dead, but they were unthinking animals. A fifth century Church Father, Gennadius of Constantinople, wrote “the offering of rational creatures is much more valuable that that of dumb ones”.
“Be transformed”, St. Paul says. He doesn’t say, “come as you are” or “stay as you are”, but be transformed! A change has to be made, and a radical one at that. You may remember my article that was published a few months ago on the problem of Catholics singing communion hymns that express Protestant teaching of the Eucharist instead of Catholic teaching and the damage this has done. I quoted the late Benedict XVI on the difference between the Lutheran belief of consubstantiation and the Catholic belief of transubstantiation. Consubstantiation says that the Body and Blood exist alongside the bread and wine. But this is not what Catholic believe. We believe in transubstantiation, that despite all appearances, the substance of bread and wine is transformed—changed—into the Body, Blood, Soul, and Divinity of Jesus Christ. This speaks to the very essence of the Christian life. To be a Christian requires a change, a conversion, a transformation of the whole person.
Allow me to give a brief real-life example. This person gave me permission to use his story in this homily. A regular Sunday-going Catholic who is a very faithful member of his church parish recently went on a True Presence Retreat. Much of what he learned there, he already knew, but being immersed in the retreat experience, it really hit him hard. This man had been living in a situation of what the Catechism calls “manifest grave sin”. This is a sinful situation that is both ongoing and by its very nature, public. This prevented him from worthily receiving Holy Communion. On that retreat, he made some hard, life-changing decisions. He realized that if he were to die today, he would die in a state of mortal sin. He realized that he had been “choosing my own satisfaction over my salvation”. He made a decision then and there to live differently so that he would no longer be in that state of sin and could receive the sacraments. This is a transformation.
“Be transformed by the renewal of your mind”. An exercise routine or a diet, while they can be good for the body and lead to good changes for the body, does not necessarily transform the whole person. What needs to be transformed is not just my appearance, what I eat, what I do, but how I think, how I feel, how I live, and most of all how I love.
“That you may discern what is the will of God, what is good and pleasing and perfect” (Rm 12:2). A mind that is in sin, that is not transformed, has a hard time knowing God’s will, knowing what is good. To paraphrase St. Thomas Aquinas, sin makes you stupid. A transformation is necessary so that we can offer the living sacrifice of our whole selves (body, heart, mind, and soul) to God.
See how rich the Word of God is, all that from just two verses.
We baptized Catholics are priests. Are we going to offer to the Lord a sacrifice that is diseased and dead or a sacrifice that is fully alive? We owe Him only the best.
