are signs of sacred things;
according to Rom. 1:20: "The invisible things of God are clearly seen
being understood by the things that are made." And yet all sensible
things cannot be called sacraments. Therefore not every sign of a
sacred thing is a sacrament.

Obj. 2: Further, whatever was done under the Old Law was a figure of
Christ Who is the "Holy of Holies" (Dan. 9:24), according to 1 Cor.
10:11: "All (these) things happened to them in figure"; and Col.
2:17: "Which are a shadow of things to come, but the body is
Christ's." And yet not all that was done by the Fathers of the Old
Testament, not even all the ceremonies of the Law, were sacraments,
but only in certain special cases, as stated in the Second Part
(I-II, Q. 101, A. 4). Therefore it seems that not every sign of a
sacred thing is a sacrament.

Obj. 3: Further, even in the New Testament many things are done in
sign of some sacred thing; yet they are not called sacraments; such
as sprinkling with holy water, the consecration of an altar, and such
like. Therefore not every sign of a sacred thing is a sacrament.

_On the contrary,_ A definition is convertible with the thing
defined. Now some define a sacrament as being "the sign of a sacred
thing"; moreover, this is clear from the passage quoted above (A. 1)
from Augustine. Therefore it seems that every sign of a sacred thing
is a sacrament.

_I answer that,_ Signs are given to men, to whom it is proper to
discover the unknown by means of the known. Consequently a sacrament
properly so called is that which is the sign of some sacred thing
pertaining to man; so that properly speaking a sacrament, as
considered by us now, is defined as being the "sign of a holy thing
so far as it makes men holy."

Reply Obj. 1: Sensible creatures signify something holy, viz. Divine
wisdom and goodness inasmuch as these are holy in themselves; but not
inasmuch as we are made holy by them. Therefore they cannot be called
sacraments as we understand sacraments now.

Reply Obj. 2: Some things pertaining to the Old Testament signified
the holiness of Christ considered as holy in Himself. Others
signified His holiness considered as the cause of our holiness; thus
the sacrifice of the Paschal Lamb signified Christ's Sacrifice
whereby we are made holy: and such like are properly styled
sacraments of the Old Law.

Reply Obj. 3: Names are given to things considered in reference to
their end and state of completeness. Now a dis
