Some evil man yesterday asked me, quite offhand, if I thought that baptism was the "new circumcision," replacing circumcision as a sacrament.
At first, I said no, because I don't see circumcision or baptism as a sacrament, only to do some research on what exactly sacraments are. Then my answer was still no, because while I can accept that they're sacraments, I don't think one replaces or supercedes the other.
So: what is a sacrament?
