§1256

The ordinary ministers of Baptism are the bishop and priest and, in the Latin Church, also the deacon. In case of necessity, any person, even someone not baptized, can baptize, if he has the required intention. The intention required is to will to do what the Church does when she baptizes, and to apply the Trinitarian baptismal formula. The Church finds the reason for this possibility in the universal saving will of God and the necessity of Baptism for salvation.
