What religion was Gustave Doré?
From his biography P. 306:
Dore said to Harford, "My friend I am a Roman Catholic, a
professed Roman Catholic. I was baptized in that Church, and I
stick to it. That is all very well and good; but if you wish to
know my real religion, I will tell it to you. It is contained in
the thirteenth chapter of St. Paul to the Corinthians."
