“Yea they sure did, the question was did God give them that right”
Yes, he did.
Matthew 16:17-19
Jesus replied, “Blessed are you, Simon son of Jonah, for this was not revealed to you by man, but by my Father in heaven. And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it. I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.”
Christ gave peter the keys to the kingdom of heaven, an authority which we see him exercise throughout Acts.
“the fact that one hears nothing more of Matthias in scripture”
This is an argument from silence.
“But the one chosen, not by men...but God (Paul)...was the churches primary teacher and theologian.”
Not so. Paul says of himself that he is the least of the Apostles. For he was not there at the beginning, and persecuted the Christians. Paul would never have said of himself that he was the primary teacher and theologian, and we must be careful not to place our own assumptions over his.
“The fact that the apostles took on themselves, at Peters urgings, the role of Christ, just shows that Peter was not infallible in matters of faith.”
Rather it shows that you’ve not understood the authority that Christ vested in Peter. It’s right there in Matthew. The power to bind and loose, the keys to the kingdom of heaven.

Sorry your reading of this is faulty...Notice that what Jesus says her is FUTURE TENSE
Peter was not singled out . The keys were actually given to the church. These scriptures are about church discipline ..NOT INFALLIBILITY OR THE PAPCY
Whatever the keys might mean to you...the "power of the key was given to all the apostles at the same time,,
Matt 18:15 But if thy brother shall offend against thee, go, and rebuke him between thee and him alone. If he shall hear thee, thou shalt gain thy brother. 16 And if he will not hear thee, take with thee one or two more: that in the mouth of two or three witnesses every word may stand. 17 And if he will not hear them: tell the church. And if he will not hear the church, let him be to thee as the heathen and publican. 18 Amen I say to you, whatsoever you shall bind upon earth, shall be bound also in heaven; and whatsoever you shall loose upon earth, shall be loosed also in heaven.
No where in scripture does Christ give away an attribute of God the Father (infallibility )
