well lets see, the Pope is infallible in matters of faith and morals but you are here to refute that....good luck!!
Just this one or all of them throughout history? While I believe that there were righteous men amongs the many Popes of history, please explain your comment vis-a-vis:
1. Pope John XII (955–964), murdered several people, gave land to a mistress, and was killed by a man who caught him 'in flagrante delicto' with his wife.
2. Pope Benedict IX (1032–1044, 1045, 1047–1048), who "sold" the Papacy, who was said to have had orgies in the Lateran palace, and who was said to have been primarily homosexual.
3. Pope Urban VI (1378–1389), who tortured Cardinals who had conspired against him and complained that he did not hear enough screaming when they were tortured.
4. Pope Alexander VI (1492–1503), the Libertine Borgia, he of multiple mistresses and multiple children.
5. Pope Leo X (1513–1521), a spendthrift, who's actions were the primary cause of the Reformation, through his selling of indulgences to raise money for his profligate spending. According to both Francesco Guicciardini and Bishop Paolo Giovio, the Pope was homosexual.
There are many others, but I submit that a Pope, being mortal, fleshly, is prone to the same sins as any other man. How many times did Jesus rebuke the Pharisees as hypocrites when they did one thing, yet instructed others not to do what they did? How then, can such Popes be 'infallible' in matters of 'morals'?
