rebaptize in the name of the Trinity." And
the reason of this is that, just as on the part of the matter, as far
as the essentials of the sacrament are concerned, any water will
suffice, so, on the part of the minister, any man is competent.
Consequently, an unbaptized person can baptize in a case of urgency.
So that two unbaptized persons may baptize one another, one baptizing
the other and being afterwards baptized by him: and each would
receive not only the sacrament but also the reality of the sacrament.
But if this were done outside a case of urgency, each would sin
grievously, both the baptizer and the baptized, and thus the
baptismal effect would be frustrated, although the sacrament itself
would not be invalidated.

Reply Obj. 1: The man who baptizes offers but his outward
ministration; whereas Christ it is Who baptizes inwardly, Who can use
all men to whatever purpose He wills. Consequently, the unbaptized
can baptize: because, as Pope Nicolas I says, "the Baptism is not
theirs," i.e. the baptizers', "but His," i.e. Christ's.

Reply Obj. 2: He who is not baptized, though he belongs not to the
Church either in reality or sacramentally, can nevertheless belong to
her in intention and by similarity of action, namely, in so far as he
intends to do what the Church does, and in baptizing observes the
Church's form, and thus acts as the minister of Christ, Who did not
confine His power to those that are baptized, as neither did He to
the sacraments.

Reply Obj. 3: The other sacraments are not so necessary as Baptism.
And therefore it is allowable that an unbaptized person should
baptize rather than that he should receive other sacraments.

SIXTH ARTICLE [III, Q. 67, Art. 6]

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.

Obj. 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.

Obj. 3: Further, Baptism is a sacrament of the greatest necessity.
Now in certain cases it seems necessary for sev
