so the Lord JESUS christ was going to build his Church on the very person who did not understand the gospel until mathew 28 , tries to stop the crucifixion by chopping a man's ear off. Denies the Lord three times, Jesus tells him " get behind me satan " . He doesn't understand that the gentiles are included until 10 years after acts 2 ? And Paul has to rebuke him for his hypocrisy. Nd then Paul mentions nothing of Peter in the book of Romans and we only have two letters compared to 13 epistles from Paul which is where the majority of CHURCH doctrine is to be found . Hmmm ?
Matthew 16 (ESV)
15 He said to them, "But who do you say that I am?" 16 Simon Peter replied, "You are the Christ, the Son of the living God." 17 And Jesus answered him, "Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven. 18 And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it. 19 I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven."
Take heed of Peter's warning in 2 Peter 3:15-18, if your interpretation of Paul's inspired writings (of which there sure is a lot), is contradictory to Jesus' own words, or contrary to that of the first hand account of the other apostles (of which there sure was a lot) who walked with Jesus / Yeshua on this earth, knowing his perfect will and walk. Consider for example his beloved disciple John, it would do no harm to expand our horizons, and be inspired by the full message of the whole word of God.
2 Peter 3 (ESV)
15 And count the patience of our Lord as salvation, just as our beloved brother Paul also wrote to you according to the wisdom given him, 16 as he does in all his letters when he speaks in them of these matters. There are some things in them that are hard to understand, which the ignorant and unstable twist to their own destruction, as they do the other Scriptures. 17 You therefore, beloved, knowing this beforehand, take care that you are not carried away with the error of lawless people and lose your own stability. 18 But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To him be the glory both now and to the day of eternity. Amen.
John 11 (ESV)
49 But one of them, Caiaphas, who was high priest that year, said to them, "You know nothing at all. 50 Nor do you understand that it is better for you that one man should die for the people, not that the whole nation should perish." 51 He did not say this of his own accord, but being high priest that year he prophesied that Jesus would die for the nation, 52 and not for the nation only, but also to gather into one the children of God who are scattered abroad.
