Whether matrimony confers grace?

Objections

Objection 1 : It would seem that matrimony does not confer grace. For, according to Hugh (De Sacram. i) "the sacraments, by virtue of their sanctification, confer an invisible grace." But matrimony has no sanctification essential to it. Therefore grace is not conferred therein.
Objection 2 : Further, every sacrament that confers grace confers it by virtue of its matter and form. Now the acts which are the matter in this sacrament are not the cause of grace (for it would be the heresy of Pelagius to assert that our acts cause grace); and the words expressive of consent are not the cause of grace, since no sanctification results from them. Therefore grace is by no means given in matrimony.
Objection 3 : Further, the grace that is directed against the wound of sin is necessary to all who have that wound. Now the wound of concupiscence is to be found in all. Therefore if grace were given in matrimony against the wound of concupiscence, all men ought to contract marriage, and it would be very stupid to refrain from matrimony.
Objection 4 : Further, sickness does not seek a remedy where it finds aggravation. Now concupiscence is aggravated by concupiscence, because, according to the Philosopher (Ethic. iii, 12), "the desire of concupiscence is insatiable, and is increased by congenial actions." Therefore it would seem that grace is not conferred in matrimony, as a remedy for concupiscence.
