This one is easy, I’ll use your argument. It’s in the scriptures so its not circular.
If its truth its truth…no rocket science here. WHo had the last word at the council of Jerusalem? Hey you got it correct, Peter!
If you are not circumcised, thank the first Pope!!!
Peter himself explained the imagery of the word stone:
1 Peter 2:4-8 ESV 4 As you come to him, a living stone rejected by men but in the sight of God chosen and precious, 5 you yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ. 6 For it stands in Scripture: “Behold, I am laying in Zion a stone,
a cornerstone chosen and precious,
and whoever believes in him will not be put to shame.” 7 So the honor is for you who believe, but for those who do not believe, “The stone that the builders rejected
has become the cornerstone,” 8 and“ A stone of stumbling,
and a rock of offense.” They stumble because they disobey the word, as they were destined to do.
Rome has done a gross injustice with their exegesis of Matthew 16:18-19
The keys to the kingdom are simply a sign of authoity linked to the Davidic line in which Jesus is the final Davidic king who here gives the keys to Peter and by extension the other apostles as we see in John 20 to declare who is bound by sin or loosed from it in regard to the instructions of God’s word… It must be understood in the context of Matthew 18:15-20 where Jesus gives specific instructions on order to the apostles and that they have the power to declare if a person is still bound in their sins or has been loosed from them by the grace of God received by faith in Jesus Christ.
Matthew 18:15-20 ESV
15 “If your brother sins against you, go and tell him his fault, between you and him alone. If he listens to you, you have gained your brother. 16 But if he does not listen, take one or two others along with you, that every charge may be established by the evidence of two or three witnesses. 17 If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector. 18 Truly, I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven. 19 Again I say to you, if two of you agree on earth about anything they ask, it will be done for them by my Father in heaven. 20 For where two or three are gathered in my name, there am I among them.”
