Whether circumcision was a preparation for, and a figure of Baptism?

Objections

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.
Objection 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.
Objection 3 : Further, it was stated above (Question [38], Articles [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.
