Absolutely - and still built on Peter by Christ, just as Jesus says.
Nonsense...Jesus is the foundation...The church was built on Jesus...He's the entire foundation...The apostles including Peter are referred to as pillars setting on the foundation...And Peter isn't even mentioned first...
Gal_2:9 And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision.
And then, Paul didn't appear to completely buy THAT story since he did not say they were pillars...He said they 'seemed' to be pillars...
You guys do alright until you get the word of God involved in your theology...
