Whether the sacraments of the Old Law caused grace?

❌ Objection 1 : It seems that the sacraments of the Old Law caused grace. For, as stated above (Article [5], ad 2) the sacraments of the New Law derive their efficacy from faith in Christ's Passion. But there was faith in Christ's Passion under the Old Law, as well as under the New, since we have "the same spirit of faith" (2 Cor. 4:13). Therefore just as the sacraments of the New Law confer grace, so did the sacraments of the Old Law.

❌ Objection 2 : Further, there is no sanctification save by grace. But men were sanctified by the sacraments of the Old Law: for it is written (Lev. 8:31): "And when he," i.e. Moses, "had sanctified them," i.e. Aaron and his sons, "in their vestments," etc. Therefore it seems that the sacraments of the Old Law conferred grace.

❌ Objection 3 : Further, Bede says in a homily on the Circumcision: "Under the Law circumcision provided the same health-giving balm against the wound of original sin, as baptism in the time of revealed grace." But Baptism confers grace now. Therefore circumcision conferred grace; and in like manner, the other sacraments of the Law; for just as Baptism is the door of the sacraments of the New Law, so was circumcision the door of the sacraments of the Old Law: hence the Apostle says (Gal. 5:3): "I testify to every man circumcising himself, that he is a debtor to the whole law."
