Becoming a priest of Jesus Christ

An apostle — that is what a Christian is, when he knows that he has been grafted onto Christ, made one with Christ, in baptism. He has been given the capacity to carry on the battle in Christ's name, through confirmation. He has been called to serve God by his activity in the world, because of the common priesthood of the faithful, which makes him share in some way in the priesthood of Christ. This priesthood — though essentially distinct from the ministerial priesthood — gives him the capacity to take part in the worship of the Church and to help other men in their journey to God, with the witness of his word and his example, through his prayer and work of atonement.
