Whether it is part of a deacon's duty to baptize?

Objections

Objection 1 : It seems that it is part of a deacon's duty to baptize. Because the duties of preaching and of baptizing were enjoined by our Lord at the same time, according to Mt. 28:19: "Going . . . teach ye all nations, baptizing them," etc. But it is part of a deacon's duty to preach the gospel. Therefore it seems that it is also part of a deacon's duty to baptize.
Objection 2 : Further, according to Dionysius (Eccl. Hier. v) to "cleanse" is part of the deacon's duty. But cleansing from sins is effected specially by Baptism, according to Eph. 5:26: "Cleansing it by the laver of water in the word of life." Therefore it seems that it belongs to a deacon to baptize.
Objection 3 : Further, it is told of Blessed Laurence, who was a deacon, that he baptized many. Therefore it seems that it belongs to deacons to baptize.
