Whether several can baptize at the same time?

❌ Objection 1 : It seems that several can baptize at the same time. For unity is contained in multitude, but not "vice versa." Wherefore it seems that many can do whatever one can but not "vice versa": thus many draw a ship which one could draw. But one man can baptize. Therefore several, too, can baptize one at the same time.

❌ Objection 2 : Further, it is more difficult for one agent to act on many things, than for many to act at the same time on one. But one man can baptize several at the same time. Much more, therefore, can many baptize one at the same time.

❌ Objection 3 : Further, Baptism is a sacrament of the greatest necessity. Now in certain cases it seems necessary for several to baptize one at the same time; for instance, suppose a child to be in danger of death, and two persons present, one of whom is dumb, and the other without hands or arms; for then the mutilated person would have to pronounce the words, and the dumb person would have to perform the act of baptizing. Therefore it seems that several can baptize one at the same time.
