The thread is about the Papacy and how it came about...not Protestant or otherwise churches....It would seem a attempt to draw the topics to Protestant churches is a diversion. Might be good to stay with topic at hand.
If someone belives in Jesus Christ and His Word there's no argument over how the Papacy came about.
(16) Simon Peter answered and said: "Thou art Christ, the Son of the living God". (17) And Jesus answering, said to him : "Blessed art thou, Simon Bar-Jona : because flesh and blood hath not revealed it to thee, but my Father who is in heaven. (18) And I say to thee: That thou art Cephas; and upon this Cephas I will build my church, and the gates of hell shall not prevail against it".
- Matthew 16 verses 16 thru 18
Christ Himself gave the name Chephas (Rock) (Matt 16:17 above) to Simon Bar-Jona who the Father chose to head His Church until Christ returns the second time the same way He established the seat of Moses to last until Christ came the first time. That makes the above verses crystal clear to anyone who is open to the Holy Spirit rather than only to their own Most High and Holy Self.
Christ Himself established the office of the Pope and all the trash talk that says otherwise is nothing but smoke and mirrors from people desperate to hide the fact that they refuse to accept what Jesus Christ Himself said and ordained. Such Self and Self Alone following folks are going to be hearing, "I never knew you" from the same Jesus Christ they absolutely refuse to believe.
Please remember that next time one of you all go off the rails.
Now we have to kill you!
