ot to baptize
in the name of the Trinity. Wherefore Gregory, writing to the Bishop
Quiricus, says: "Those heretics who are not baptized in the name of
the Trinity, such as the Bonosians and Cataphrygians" (who were of
the same mind as the Paulianists), "since the former believe not that
Christ is God" (holding Him to be a mere man), "while the latter,"
i.e. the Cataphrygians, "are so perverse as to deem a mere man," viz.
Montanus, "to be the Holy Ghost: all these are baptized when they
come to holy Church, for the baptism which they received while in
that state of error was no Baptism at all, not being conferred in the
name of the Trinity." On the other hand, as set down in De Eccles.
Dogm. xxii: "Those heretics who have been baptized in the confession
of the name of the Trinity are to be received as already baptized
when they come to the Catholic Faith."

Reply Obj. 4: According to the Decretal of Alexander III: "Those
about whose Baptism there is a doubt are to be baptized with these
words prefixed to the form: 'If thou art baptized, I do not rebaptize
thee; but if thou art not baptized, I baptize thee,' etc.: for that
does not appear to be repeated, which is not known to have been done."

Reply Obj. 5: Both sacraments, viz. Baptism and the Eucharist, are a
representation of our Lord's death and Passion, but not in the same
way. For Baptism is a commemoration of Christ's death in so far as
man dies with Christ, that he may be born again into a new life. But
the Eucharist is a commemoration of Christ's death, in so far as the
suffering Christ Himself is offered to us as the Paschal banquet,
according to 1 Cor. 5:7, 8: "Christ our pasch is sacrificed;
therefore let us feast." And forasmuch as man is born once, whereas
he eats many times, so is Baptism given once, but the Eucharist
frequently.

TENTH ARTICLE [III, Q. 66, Art. 10]

Whether the Church Observes a Suitable Rite in Baptizing?

Objection 1: It seems that the Church observes an unsuitable rite in
baptizing. For as Chrysostom (Chromatius, in Matth. 3:15) says: "The
waters of Baptism would never avail to purge the sins of them that
believe, had they not been hallowed by the touch of our Lord's body."
Now this took place at Christ's Baptism, which is commemorated in the
Feast of the Epiphany. Therefore solemn Baptism should be celebrated
at the Feast of the Epiphany rather than on the eves of Easter and
Whitsunday.

Obj. 2: Further
