(Unless, of course, the circumcision was for a genuine medical problem.)

The New Testament is the basis of the Christian (Catholic) religion and forbids circumcision very clearly:

“I, Paul, tell you that if you be circumcised, Christ will be of no advantage to you.” – Gal 5:2

“Let him not be circumcised! Circumcision is nothing. And uncircumcision is the keeping of the commandments of God.” - 1 Cor. 7:19

“Watch out for those wicked men who say you must be circumcised… Beware of the mutilation. For it isn't the cutting of our bodies that makes us children of God; it is worshiping him with our spirits.” – Phil 3:2-3

“And even those who advocate circumcision don’t really keep the whole law. They only want you to be circumcised so they can claim you as their disciples.” – Gal 6:13

“…those who insist on circumcision for salvation. They must be silenced. By their wrong teaching, they have already turned whole families away from the truth. Such teachers only want your money” – Titus 1:10-11

“And I testify again to every male who receives circumcision, that he is in debt to keep the whole Law. You who do so have been severed from Christ…you have fallen from grace.” - Gal 5:3

The Christian religion abolishes pagan blood sacrifice and rituals. Doing so is an insult to God. Circumcision is an insult to God.
