Religion is natural to man, almost as natural as breathing. Men are therefore naturally inclined to cling to the religion they already possess, until the truth is put before them and clearly apprehended by them.

Nor can they be compared with Catholicity, which is so definite, and which makes such concrete demands upon the whole man.
