One can argue is/is not the Rock on which Jesus builds His Church 'til the cows come home. There are things in the Bible that are irrefutable:
Jesus builds the Church
No arguemnat it is a statement of Fact it is not Peter, Context i get in trouble for it all the time but here it is missused to decieve men.
Mat 16:15 He saith unto them, But whom say ye that I am?
Mat 16:16 And Simon Peter answered and said, Thou art the Christ, the Son of the living God.
Mat 16:17 And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.
Mat 16:18 And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.
Now please read 16:17, it is what Jesus was showing Simon, you know" revelation" it is not who as he was talking to Peter not about Peter, that he is building His "ecclesia", (correct word) upon revelation,
This bit
1Co_2:10 But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.
And its teh reason why churches are failing, they have no revelation its all mens doctrines and teachings.
And i wrote all that without different colours or bold,
Mat_11:25 At that time Jesus answered and said, I thank thee, O Father, Lord of heaven and earth, because thou hast hid these things from the wise and prudent, and hast revealed them unto babes.
