[madnak]

And why, when God made the covenant with Abraham, did he require Abraham to take the foreskins of all his family and servants, and to see to it that the foreskins of his family and servants throughout his descendants were also cut off? Keep in mind that this was definitely unhealthy at the time.

Now, this is the specific sign that God requested to represent his chosen people. It's irrelevant whether the law applies now. The point is that of all the possible signs God could have chosen (hey, he could have simply waved a hand and "stamped" everyone with a mark), he chose the removal of the outside of the penis as the great indication of His people. Did he have a good reason for doing this, or is he just a pervert?
