God called several people by different names. One thing we can be assured of is that He did not call Simon Peter to change who the church would be built on.
1 Cor. 3:11, "For no man can lay a foundation other than the one which is laid, which is Jesus Christ,"
Jesus also called Peter Satan in that same conversation.
Matthew 16:23 But he turned, and said unto Peter, Get thee behind me, Satan: thou art an offence unto me: for thou savourest not the things that be of God, but those that be of men.
Should we then understand that since Jesus called Simon Satan that the Catholic Church is build on Satan? After all, Jesus called him both names in the same conversation and He called him Satan after He called him Peter.
I can think of one He should call obfuscator. Was Peter named Rock by Jesus?
