Wicked sons do not have the Holy Ghost in the same way as do beloved sons, and yet they do have Baptism. So, too, heretics do not have the Church as Catholics have, even though they have Baptism.
I read in the newspaper that the Catholic Church finally decided that it had been theologically improper to try to convert the Jews. Whoops! Sorry for all those inquisitions, crusades, and autos-da-fe. Previous popes were wrong - infallible, perhaps, but wrong.
I have never been brought up a Catholic - I mean, a Roman Catholic - we're all Catholics, aren't we? We're Protestant Catholics, whether we're from Methodist or Baptist or what.
Why persist in walking difficult and toilsome paths? There is no repose where you are seeking it. Search as you like, it is not where you are looking. You are seeking a happy life in the realm of death, and it will not be found there. How could life be happy where there is no life at all?
