Pizarro was a life long Catholic. He never did anything that would indicate that he was a Protestant. He was baptized Catholic, worshipped ONLY in Catholic churches - might never have even seen a Protestant one - and helped build a number of Catholic churches himself. For crying out loud he laid the first stone of the CATHOLIC CATHEDRAL in Lima!!! Where do you get these bizarre ahistorical ideas of yours? Next you’ll be claiming there were Vikings in Russia in 1700! Oh, wait...you already did.
Bet you forgot that ~ the church was UNHAPPY with him and his men.
What you are forgetting is that in the early 1500s the French Religious Wars are long in the future, Protestants have not yet begun worshipping separately, and the Thirty Years war is a full century away.
Get your head out of your lower orifice and take a look at the time lines.
Ask yourself ~ what happened to the Spanish Protestants?
Although schism was averted in Spain itself, that was simply because people who didn't want to live under the thumb of the priestly caste could leave ~ and they did.
