that is true.
and even if peter is also a sinful man like each one of us, it does not hinder god to grant the grace/gift of infallibility. of course, this is the promise of the guidance of the holy spirit. peter wrote his letters under the guidance of the holy spirit. the same goes true with the other men who wrote the words in the bible.
I just love the way RCs compare Peter to their evil leaders and now to themselves. I personally never ever considered harming a child, would never commit a rape, never been to an orgie. I praise God for that. You might consider yourself and Peter in the same league as your evil leaders but we are not all the same.
The sins your leaders commit especially those who ignored all the sin the others were doing is evidence of how far your leaders are from God. It shows how rebellious they are. They are not guided by the HS and no matter how often RCs claim it, their leaders actions reveal the truth. The other apostles did not commit the sins of your leaders either.
Isn't it a joke that RCs claim their are different levels of sin, put Peter, the apostles and all of us on the same level as Judas and their leaders who rape, who teach false doctrines, who defraud governments, who organise and particape in orgies, who condone murder, torture and persecution, who have children outside marriage, who harm, molest and abuse children. These are just some of the sins of their leaders throughout the centuries. They do not meet the scriptural requirements for the leaders of the real church.
RCs need to stop covering up the evil of their leaders throughout the centuries, they need to read the signs of what their leaders really are.
