FIRST ARTICLE [III, Q. 70, Art. 1]
Whether Circumcision Was a Preparation For, and a Figure of Baptism?
Objection 1: It seems that circumcision was not a preparation for, and a figure of Baptism. For every figure has some likeness to that which it foreshadows. But circumcision has no likeness to Baptism. Therefore it seems that it was not a preparation for, and a figure of Baptism.
Obj. 2: Further, the Apostle, speaking of the Fathers of old, says (1 Cor. 10:2), that "all were baptized in the cloud, and in the sea": but not that they were baptized in circumcision. Therefore the protecting pillar of a cloud, and the crossing of the Red Sea, rather than circumcision, were a preparation for, and a figure of Baptism.
Obj. 3: Further, it was stated above (Q. 38, AA. 1, 3) that the baptism of John was a preparation for Christ's. Consequently, if circumcision was a preparation for, and a figure of Christ's Baptism, it seems that John's baptism was superfluous: which is unseemly. Therefore circumcision was not a preparation for, and a figure of Baptism.
On the contrary, The Apostle says (Col. 2:11, 12): "You are circumcised with circumcision, not made by hand in despoiling the body of the flesh, but in the circumcision of Christ, buried with Him in Baptism."
