"I will bestow this grace unto you,confident that without too long a delay the See of Peter will be occupied by a successor of Peter who is perfectly Catholic,and into whose hands you will be able to put back the grace of your episcopy so that he may confirm it."
I think you mistakenly posted the wrong letter if your intent was to prove that archbishop Lefebvre "does not accuse the Pope himself of being and Antichrist."(your words) See first italicized post which clearly states that he believes the Pope and those in positions of authority are anti-Christs.
The second italicized post confirms the first. Now please let's stop playing silly games and work together to save the Catholic Church and Western Civilization. Fight the liberals/modernists/progressives/iinfiltrators/homosexuals/bishops who cover/imposters and the devil and call the dogs off of those of us who are orthodox,traditional,conservative,obedient Catholics who only want to save the Church Christ established on earth for the salvation of souls for the God who created us all.
Here is what the Archbishop advised his bishops:
"I beseech you TO REMAIN ATTACHED TO THE SEE OF PETER, to the Roman Church, Mother and Mistress of all Churches, in the integral Catholic Faith, expressed in the various creeds of our Catholic Faith, in the Catechism of the Council of Trent, in conformity with what you were taught in your seminary. Remain faithful in the handing down of this Faith so that the Kingdom of Our Lord may come."
How is this in any way consistent with calling the Pope an antichrist? Clearly he was referring to the apostates who people the highest posts in the Vatican and not to the Pope himself--and in this, he spoke the truth.
As for your second point about playing silly games and working together--you trivialize the conflict by reducing it to such terms. The conflict we are in is not a silly game, it is a deadly struggle. There is no possibility of working with those committed to destroying the Catholic faith.
