Could someone explain the following verses? I Cor 10:4 says the rock was Jesus. I Cor 3:11 says Jesus is the foundation. Eph 2:20 says Jesus is the cornerstone. Psalm 18:2 says the Lord is my rock. 2 Sam 22:2 says the Lord is my rock. If all these verse and more say that Jesus is the rock and the foundation, why would Jesus then call Peter the rock and build a church on Peter.
I believe Paul was identifying certain passages in the Hebrew, that refer to the Rock of Salvation (Yeshua).
Paul had studied the Tanakh about the Chief Corner Stone (Psalms 118), and created an ideology of us being the Bricks of the Temple of the Lord.
As far as I can see Paul understood we have one God, and one Lord; where he believed Yeshua to be the Lord incarnate, and the God Most High above him.
In my understanding of the Bible, when Yeshua/Yehoshua called Simon petros (Matthew 16:18), that fulfils prophecy in Zechariah 3:9, and Isaiah 8:14-16.
Petros implies a small rock, like a Pebble; Petras is a bigger rock, like a cliff, or foundation stone.
In the Parable of the Seed Sower, the seeds that fall on 'Stony Ground' is plural of Petros - 'Petrodes'.
I don't think Yeshua said the church was built on Simon, more that he'd help establish his Church down here near Hell.
Take into account straight after Yeshua gave Simon this calling, he calls Simon satan (Matthew 16:23), saying 'he follows the ways of man, not God'.
In my opinion.
