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.
The fashion just now is a Roman Catholic frame of mind with an Agnostic conscience: you get the mediaeval picturesqueness of the one with the modern conveniences of the other.
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.
