Christ did not establish the “church” on Peter, another sinner.
It is a tragedy that the Catholic church didn’t acknowledge the obvious:
Eph. 2:5-9
[5] Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)
[6] And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:
[7] That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus.
[8] For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
[9] Not of works, lest any man should boast.
I really believe GOD has it right and man who disagrees with GOD; has a self serving agenda ... . It’s best to listen to God and not other sinners ... .
