YOUCAT Question n. 198 - Who can administer Baptism?

(Youcat answer) Normally a Bishop, a Priest, or a Deacon administers the sacrament of Baptism. In an emergency, any Christian, indeed anyone, can baptize by pouring water over the head of the recipient and pronouncing the baptismal formula, “I baptize you in the name of the Father and of the Son and of the Holy Spirit.”

A deepening through CCC

(CCC 1256) The ordinary ministers of Baptism are the bishop and priest and, in the Latin Church, also the deacon (Cf. CIC, can. 861 § 1; CCEO, can. 677 § 1). In case of necessity, anyone, even a non-baptized person, with the required intention can baptize (CIC, can. 861 § 2), by using the Trinitarian baptismal formula. The intention required is to will to do what the Church does when she baptizes. The Church finds the reason for this possibility in the universal saving will of God and the necessity of Baptism for salvation (Cf. 1 Tim 2:4).

Reflecting and meditating 

(Youcat comment) Baptism is so important that even a non-Christian can administer it. In doing so, however, he must have the intention of doing what the church does when she baptizes.

(CCC Comment)

(CCC 1284) In case of necessity, any person can baptize provided that he have the intention of doing that which the Church does and provided that he pours water on the candidate's head while saying: "I baptize you in the name of the Father, and of the Son, and of the Holy Spirit."    

(The next question is: Is Baptism in fact the only way to salvation?)
