Then Rome should have put a concordance in the bible so ignorant folks would know EXACTLY how to interpret the words.

A person who is baptized in the Catholic Church becomes a Catholic at that moment. One’s initiation is deepened by confirmation and the Eucharist, but one becomes a Catholic at baptism. This is true for children who are baptized Catholic (and receive the other two sacraments later) and for adults who are baptized, confirmed, and receive the Eucharist at the same time.
