“Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything that I have commanded you. And remember, I am with you always, to the end of the age.” (Mt.28:19-20)

“Baptism imprints on the soul an indelible spiritual sign, the character, which consecrates the baptized person for Christian worship.” (CCC 1280)

The sacrament of Baptism initiates us into the mystery of Christ. It is the essential rite to eternal life, and the beginning point of the whole Christian experience. (CCC 1213) In Baptism, God first demonstrates His self-communication to us. It imprints His indelible mark upon our souls configuring us to the life, death, and resurrection of Jesus Christ. The character of Christ is irrevocably sealed upon our minds and souls, configuring us to a new and eternal spiritual reality. (CCC 1272) It transforms who we are. A permanent ontological change takes place to our very being. Just as a material object or person is visibly sealed with a mark, defining who or what it is, or whose property it might be, so too, in Baptism, God marks our immaterial souls invisibly and permanently, claiming us as His own. It sets us apart. It can only be done once, and nothing can undo it. It is a necessary transformation. Jesus attests to it, saying, “Very truly, I tell you, no one can enter the kingdom of God without being born of water and Spirit.” (Jn.3:5) Baptismal water is a graced sign, a real symbol, which efficaciously applies the invisible grace it signifies. It does in reality, the sign it points to. We are washed of Original Sin, purified of all of our sins, and regenerated to eternal life. It consecrates us into the sacramental character of Christ’s paschal mystery, impressing upon us His saving grace of the Cross. (SC, 6) We are sealed with Christ’s imprimatur, conforming us to the God-man. (2 Cor. 1:21-22) He alone conquered sin, and death itself, so that by faith and grace, we too, who are flesh and blood mortals, may partake in His supernatural life. Baptism is necessary because Christ alone overcame death. We need His divine life in us, so we too will rise to eternal life. Baptism anticipates our own resurrection. Through it, we are grafted into communion with the Easter mysteries. The mystery of Christ becomes alive to us, and in us. Christ in His life, and in His Passion and suffering, and all that He was in His eternal and divine humanity, begins to unfold and live out in our individual lives. When we are immersed into the water, we are brought into His death, and rising from the water, we are brought into His life and resurrection. (Rom. 6:3-4) As the Catechism says, “It signifies and actually brings about death to sin and entry into the life of the Most Holy Trinity through configuration to the Paschal mystery of Christ.” (CCC 1239) We are made into a new living, Trinitarian reality; spiritually reordered towards the Father, configured to the Son, and filled with the Holy Spirit. We become adopted children of God, by faith and grace; baptized into the Son of God, we are made partakers in the divine nature by proxy, as He is in reality.

We are indeed remade into this new holy status as children of God, and temples of the Holy Spirit, and co-heirs with Christ. It makes us, first and foremost, Christian, and members of the Church, the Body of Christ, and gains us access to divine grace in the rest of the sacraments. It is our foundation for the supernatural life. But, it is also the first moment of a lifelong phenomenon of conversion. Baptism is more than just a single event, or a static state; it transforms us in such a way that we are perpetually drawn deeper into the living reality of Christ. It allows us to engage in the sacramental life and realize the mysteries of Christ in our being. It establishes a new dynamic in our consciousness, where our everyday circumstances are reinterpreted and contextualized within the divine humanity of Christ. Our humanity is elevated and divinized. We are afforded special offices. One of these is our incorporation into the common priesthood of the faithful, the baptized, and the ordinary. With a sacred chrism, the oil consecrated by the bishop, the newly baptized is anointed into Christ as “priest, prophet, and king.” (CCC 1241) We become sharers in Christ’s one eternal priesthood. As Lumen Gentium, the Dogmatic Constitution of the Church, says, “The baptized, by regeneration and the anointing of the Holy Spirit, are consecrated as a spiritual house and a holy priesthood.” (LG, 10) Even as Christ is the one true and eternal Mediator between God and man, He still graciously saw fit that we should also participate, to varying degrees, in His priestly office. As part of our baptismal right and dignity, we can exercise that priestly office by virtue of our association in Christ’s life, passion, and redemptive sacrifice.

But, what are our priestly functions? Scripture and the Church say we are to make spiritual sacrifices. We are to offer up interiorly all of our actions, words, deeds, suffering, successes, and all that we do, for the glory of God and for the intercession of souls. The magisterium teaches that the baptized should “present themselves as a living sacrifice, holy and pleasing to God.” (LG, 10 ) Every common thing in our ordinary existence can be extended towards God as a sacrifice in our common priesthood. We can offer up everything, including our prayers, sacrifices, fasting, bodily weaknesses, illness, even patiently enduring the things that annoy us, or nearly anything that may otherwise seem useless and worthless in the eyes of the world. God’s eternal priesthood is mediated in the implements of our material world. Our physical operations can have spiritual significance. We can exercise our priesthood, in such a way, that we can, in effect, “sacramentalize” all that we do. That is, we spiritualize our activity through faith and with the intention of offering reparation to God. This is how we become living sacrifices. As the magisterium explains, we can “exercise that priesthood in receiving the sacraments, in prayer and thanksgiving, in the witness of a holy life, and by self-denial and active charity.” (LG, 10) By ourselves, a branch separated from the vine, our actions have no spiritual power. But, united with Christ, in the power of the Holy Spirit, our actions can be spiritually efficacious for reparation of our sins and the sins of others. This is our role in the communion of saints. We are mediators. Through initiation in Baptism and the imprinting of Christ’s priestly seal upon us, we become priests. We can use our willful intention to please God, in a particular activity, invoke the anointing of the Holy Spirit, and raise that up as a form of worship. So, we can, for illustration, use our being hungry on any given afternoon, or say, being stuck behind a slow driver in our morning commute, to invoke the Holy Spirit, and offer these annoyances up to God for the sanctification of souls. These are just two minor examples, but the possibilities are nearly endless. St.Paul explains these spiritual sacrifices. He says, “I am now rejoicing in my sufferings for your sake, and in my flesh I am completing what is lacking in Christ’s afflictions for the sake of his body, that is, the church.” (Col.1:24) Christ deemed us worthy to take part in His priestly ministry, and left for us a portion of the redemption to offer up to the Father. He made us a living Church, actively carrying on His mission. Christ’s presence and power remain hidden now sacramentally, just as it did in His life then when He walked the earth.  Some people today see just bread and wine, and not the body and blood of Christ, as before they saw just the carpenter’s son, and not the Son of God.  Christ continues His priestly mediation for the world today through us. In this vein, St.Paul is dutifully acting out his priestly character. He offers intercession and mediation for the Church, through his own sufferings, in unity with the sufferings of Christ. We are called to do the same. Christ has deputized us. He appointed us His priests. It is our role to live as mediators and intercessors here on earth in imitation of Him. We are to stand in the breach for those entrusted to us.  Baptism is everything, but it’s also just the beginning.
