None of the quotes you posted contradict the fact that Augustine recognized papal authority. Certainly Augustine didn't see a contradiction.
AugustineAugustine was the Bishop of Hippo and in communion with Rome. He could not have rejected the authority of the pope and have remained a bishop."Among these [apostles] Peter alone almost everywhere deserved to represent the whole Church. Because of that representation of the Church, which only he bore, he deserved to hear I will give to you the keys of the kingdom of heaven" (Sermons 295:2 [A.D. 411]).
"Some things are said which seem to relate especially to the apostle Peter, and yet are not clear in their meaning unless referred to the Church, which he is acknowledged to have represented in a figure on account of the primacy which he bore among the disciples. Such is I will give unto you the keys of the kingdom of heaven, and other similar passages. In the same way, Judas represents those Jews who were Christs enemies" (Commentary on Psalm 108 1 [A.D. 415]).
"Who is ignorant that the first of the apostles is the most blessed Peter?" (Commentary on John 56:1 [A.D. 416]).
Do you love your pope Francis?
STA, you need to learn something other than Catholic teachings that give you incomplete Biblical information mixed with all kinds of visions and apparitions and bright light phenomena.
ALL of the quotes I posted contradict the fact that today's church of ROME teaches something ENTIRELY different than these biblical truths.
