Whether every sign of a holy thing is a sacrament?

Objections

Objection 1 : It seems that not every sign of a sacred thing is a sacrament. For all sensible creatures are signs of sacred things; according to Rm. 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.
Objection 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 FS, Question [101], Article [4]. Therefore it seems that not every sign of a sacred thing is a sacrament.
Objection 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.
