Reply Obj. 1: The Fathers of old had faith in the future Passion of Christ, which, inasmuch as it was apprehended by the mind, was able to justify them. But we have faith in the past Passion of Christ, which is able to justify, also by the real use of sacramental things as stated above.
Reply Obj. 2: That sanctification was but a figure: for they were said to be sanctified forasmuch as they gave themselves up to the Divine worship according to the rite of the Old Law, which was wholly ordained to the foreshadowing of Christ's Passion.
Reply Obj. 3: There have been many opinions about Circumcision. For, according to some, Circumcision conferred no grace, but only remitted sin. But this is impossible; because man is not justified from sin save by grace, according to Rom. 3:24: "Being justified freely by His grace."
Wherefore others said that by Circumcision grace is conferred, as to the privative effects of sin, but not as to its positive effects. But this also appears to be false, because by Circumcision, children received the faculty of obtaining glory, which is the ultimate positive effect of grace. Moreover, as regards the order of the formal cause, positive effects are naturally prior to privative effects, though according to the order of the material cause, the reverse is the case: for a form does not exclude privation save by informing the subject.
Hence others say that Circumcision conferred grace also as regards a certain positive effect, i.e. by making man worthy of eternal life, but not so as to repress concupiscence which makes man prone to sin. And so at one time it seemed to me. But if the matter be considered carefully, this too appears to be untrue; because the very least grace is sufficient to resist any degree of concupiscence, and to merit eternal life.
And therefore it seems better to say that Circumcision was a sign of justifying faith: wherefore the Apostle says (Rom. 4:11) that Abraham "received the sign of Circumcision, a seal of the justice of faith." Consequently grace was conferred in Circumcision in so far as it was a sign of Christ's future Passion, as will be made clear further on (Q. 70, A. 4). _______________________
