Did you know that the hymn "Faith Of Our Fathers" was written by a man who had recently converted to Roman Catholicism? The third stanza (which has been altered in "Protestant" hymnals), was written like this:
"Faith of our fathers! Mary's prayers
Shall win our country back to thee;
And through the truth that comes from God
England shall then indeed be free.
Faith of our fathers, holy faith!
We will be true to thee till death."
