Hmmmm, this is way too long for me to read every post, but it does interest me because I have six children (one to be born in Oct.), and four are boys. My husband is Jewish (he converted six years after our marriage), and I always thought (as a lukewarm Catholic at the time of our marriage, with no real thought that my hubby would convert) that we would circumsize.
However, we just couldn’t bring ourselves to do it, and since we had both agreed that our kids would be raised Catholic, we didn’t see any reason for it (if our kids were to be raised Jewish, we could see a religious reason for it). So, we didn’t do it. For us personally, it was a good decision. There have been no problems whatsoever.
Now, as devout Catholics, both my husband and I understand baptism as the fulfillment of circumcision.
As far as why God asked for circumcision as the sign of His covenant with the Hebrew people, I remember hearing an AMAZING explanation of that while listening to a Christopher West seminar on tape. It had to do with the Jewish bridegroom sacredly revealing himself to his bride upon their consummation, and it (as all nuptial symbolism does) finds its fulfillment in Christ on the Cross. Christ is the ultimate Bridegroom and as He gave His life for His Bride (the Church), He was not wearing a loincloth as artwork depicts. The Romans were not interested in preserving the modesty of those whom they were crucifying, so Jesus would have been unclothed.
Anyway, Chris West goes on in his explanation, and since it has been years since I’ve heard it, I had better just leave those of you who are interested to find his materials. It is breathtaking, though. And it gave me a whole new perpective on the theology of circumcision.
