Okay? So you cut off the flesh to represent the removal of sins from the flesh? Still... the penis? Why not a fingernail or even my little toe? Does the ol' johnson really need to get wacked... er, cut off I mean?
If ya really wanna know:
St. Thomas holds that circumcision was a figure of baptism: this retrenches and restrains the animal man as that removed a part of his body -- which physical act indicated the spiritual effect of the sacrament (De Sac., Summa, III, Q. lxx, a. 1). He gives three reasons why the organ of generation rather than any other was to be circumcised:
1. Abraham was to be blessed in his seed;
2.The rite was to take away original sin, which comes by generation;
3. It was to restrain concupiscence, which is found especially in the generative organs (III, Q. lxx, a. 3). [apparently St. Thomas thought that sexual desire would be lessened by circumcision - a doctor he wasn't - no1]
According to his teaching, as baptism remits original sin and actual sins committed before its reception, so circumcision remitted both, but ex opere operantis, i.e. by the faith of the recipient, or, in the case of infants, by the faith of the parents.
