of words."

The Baptismal character is both reality and sacrament: because it is
something real signified by the outward washing; and a sacramental
sign of the inward justification: and this last is the reality only,
in this sacrament--namely, the reality signified and not signifying.

Reply Obj. 1: That which is both sacrament and reality--i.e. the
character--and that which is reality only--i.e. the inward
justification--remain: the character remains and is indelible, as
stated above (Q. 63, A. 5); the justification remains, but can be
lost. Consequently Damascene defined Baptism, not as to that which is
done outwardly, and is the sacrament only; but as to that which is
inward. Hence he sets down two things as pertaining to the
character--namely, "seal" and "safeguarding"; inasmuch as the
character which is called a seal, so far as itself is concerned,
safeguards the soul in good. He also sets down two things as
pertaining to the ultimate reality of the sacrament--namely,
"regeneration" which refers to the fact that man by being baptized
begins the new life of righteousness; and "enlightenment," which
refers especially to faith, by which man receives spiritual life,
according to Habac 2 (Heb. 10:38; cf. Habac 2:4): "But (My) just man
liveth by faith"; and Baptism is a sort of protestation of faith;
whence it is called the "Sacrament of Faith." Likewise Dionysius
defined Baptism by its relation to the other sacraments, saying
(Eccl. Hier. ii) that it is "the principle that forms the habits of
the soul for the reception of those most holy words and sacraments";
and again by its relation to heavenly glory, which is the universal
end of all the sacraments, when he adds, "preparing the way for us,
whereby we mount to the repose of the heavenly kingdom"; and again as
to the beginning of spiritual life, when he adds, "the conferring of
our most sacred and Godlike regeneration."

Reply Obj. 2: As already stated, the opinion of Hugh of St. Victor on
this question is not to be followed. Nevertheless the saying that
"Baptism is water" may be verified in so far as water is the material
principle of Baptism: and thus there would be "causal predication."

Reply Obj. 3: When the words are added, the element becomes a
sacrament, not in the element itself, but in man, to whom the element
is applied, by being used in washing him. Indeed, this is signified
by those very words which are added to the element, when we say: "I
