Whether a sacrament imprints a character on the soul?

❌ Objection 1 : It seems that a sacrament does not imprint a character on the soul. For the word "character" seems to signify some kind of distinctive sign. But Christ's members are distinguished from others by eternal predestination, which does not imply anything in the predestined, but only in God predestinating, as we have stated in the FP, Question [23], Article [2]. For it is written (2 Tim. 2:19): "The sure foundation of God standeth firm, having this seal: The Lord knoweth who are His." Therefore the sacraments do not imprint a character on the soul.

❌ Objection 2 : Further, a character is a distinctive sign. Now a sign, as Augustine says (De Doctr. Christ. ii) "is that which conveys something else to the mind, besides the species which it impresses on the senses." But nothing in the soul can impress a species on the senses. Therefore it seems that no character is imprinted on the soul by the sacraments.

❌ Objection 3 : Further, just as the believer is distinguished from the unbeliever by the sacraments of the New Law, so was it under the Old Law. But the sacraments of the Old Law did not imprint a character; whence they are called "justices of the flesh" (Heb. 9:10) by the Apostle. Therefore neither seemingly do the sacraments of the New Law.
