If that be so Anglicans are Catholics after all, a thing which I have heard you repeatedly deny.

In virtue of their valid Baptism they are radically Catholics. But despite affiliation with the Catholic Church by valid Baptism, one can exclude himself from the true and visible Church by conscious heresy or schism. If a child is baptized validly in the Church of England, that child is a Catholic and remains a Catholic until it comes to the age of reason and adopts heretical and schismatical Anglicanism for itself. For example, if I receive an adult Anglican together with his infant son into the Catholic Church, and it is certain that both have been baptized validly, I have to ask the father to abjure heresy and to profess formally his submission to the Catholic Church. But nothing is done as regards the infant son. It is simply taught Catholic doctrine and brought up as a Catholic. Its Baptism, although performed in the Anglican Church, made it a member of the Catholic Church. In that sense every valid Sacrament, even marriage, belongs to the Catholic Church. Usually, however, converts to the Catholic Church are baptized again conditionally, lest there should be any radical defect in their first submission to that rite.
