“This Rock” is NOT Peter.”
Of course it is, it isn’t a interpretation it is what Jesus actually said. Peter, whom Jesus named actually translates to rock...
Look up Catholic teachings from Catholic sources, that’s the only way you will get to the truth...
You are looking at the hole, not the Donut.
If Yeshua has meant Peter, the person, Yeshua would said “you ‘Petros, but Yeshua did not say “you” or “Petros”. Petros, a named derived form “petra” or “rock” but being a person NOT “a rock”. Petros (not petra) was a person, not a thing, not a “this”.
And what Yeshua said was “on this rock (petra”; not “you Petros”.
And “this rock” refers as Yeshua directly pointed out was Peter’s (Petros) answer, not Peter. And Peters answer was the correct answer the question from Yeshia - who do you say I am.
That answer was “that you are the Christ”, and THAT the answer (the belief and faith that Yeshua is the Christ”< is the “that rock” (that “petra” not ‘you Petros”) THAT Yeshua said was the foundation of His Church. That belief, not Peter.
