Over the past several weeks, we have been reflecting on the vocation of the laity. We began with who the laity are: baptized members of Christ’s Body. Last week, we considered where their mission is lived: in the vineyard of family life, work, culture, and the wider world. Through Baptism, the faithful share in the threefold mission of Christ as Priest, Prophet, and King. This week, let us focus on what it means to share in His priesthood. 

At its heart, a priest is a bridge between God and creation, receiving God’s gifts and offering creation back to Him in worship, thanksgiving, and sacrifice. The Bible never directly calls Adam a priest, but Genesis presents his vocation in priestly terms. Eden is God’s sanctuary, and Adam is placed there to serve and guard it. His task is to receive creation from God and order it back toward God. Sin breaks that communion, and the bridge is damaged. 

Throughout the Old Testament, priesthood becomes increasingly associated with sacrifice. Israel’s priests stand before God on behalf of the people, yet their sacrifices cannot finally heal the wound of sin. They point beyond themselves toward the One who can. 

Jesus is the new Adam and the great High Priest. He does not simply offer another sacrifice like those of the Temple. He offers Himself. On the Cross, priest and victim become one. In His humanity, Jesus gathers humanity and creation into Himself; as the Son, He brings them back to the Father. In His own person, He becomes the bridge that overcomes the effect of sin. 

There is ultimately only one bridge: Jesus Christ. This is why Saint Peter proclaims, “There is no salvation through anyone else.” The Church’s ancient teaching that “outside the Church there is no salvation” is not a claim of superiority. It points to the deeper truth that there is one Savior, one Priest, and one way to the Father: Jesus Christ. 

The Church is Christ’s Body, the people joined to Him and drawn through Him into communion with the Father. Baptism therefore does more than enroll us in an organization. It incorporates us into Christ, and because we belong to His Body, we share in His priesthood. The whole Church is a priestly people. 

The laity exercise their baptismal priesthood not primarily by doing things is the sanctuary, but by offering the ordinary substance of their lives: work, marriage, family life, prayer, suffering, service, disappointments, and sacrifices. United to Christ, all of this becomes a “living sacrifice” offered to the Father. 

The priesthood of the baptized and the ministerial priesthood are not rivals. The ordained priest is not simply a Christian with “more” priesthood. The two differ essentially, yet both participate in the one priesthood of Jesus Christ and are ordered to one another. The ordained priest acts sacramentally in the person of Christ the Head: preaching the Word, shepherding the Church, forgiving sins, and above all celebrating the Eucharist. He does not replace the priestly people; he serves them so that their baptismal priesthood may flourish. 

Put simply, ordination is not the goal of Christian life; holiness is. Yet Christ gives His Church ordained ministers so that His priestly people can be nourished, united, and equipped for mission. The goal is not everyone doing the same things but rather one of co-responsibility with each vocation fully alive and ordered toward the same mission. 

This helps us avoid the two dangers Saint John Paul II warned about: reducing the vocation of the laity to tasks inside the Church, and separating faith from ordinary life. The baptismal priesthood is lived precisely by bringing the world to God, and God to the world, through Christ. 

We see something of this in Sunday’s readings. In Isaiah, Eliakim receives the key of the House of David and authority to serve as a father to the people. In the Gospel, Peter confesses Jesus as “the Christ, the Son of the living God,” and Jesus entrusts him with the keys of the Kingdom. Authority in the Church is given for service: to strengthen, unite, and build up the people Christ sends into the world. Saint Paul echoes the doxology at Mass: “from him and through him and for him are all things.” 

The Eucharist is the source and summit of the Christian life. Each Sunday, as God’s priestly people, we bring our families, work, joys, wounds, responsibilities, and hopes to the altar. The ordained priest gathers these offerings into Christ’s Eucharistic sacrifice, and God gives us the grace to carry Christ from the altar back into the world.
