So Peter, instead of Jesus, is the chief corner stone of your church. Peter, and the prophets, say otherwise. Therefore your church’s interpretation fails the test of scriptural proofs.
Nonsense.
The “keys of the kingdom” image comes right out of Isaiah. It means that Peter (and his successors) are the Prime Ministers of the kingdom.
Why do you argue against Catholicism with lies—such as “Peter, instead of Jesus, is the chief cornerstone of your church”? That is just a lie about what the Catholic Church teaches about itself.
What good is supposed to come from an argument based on a falsehood?
This reminds me of all those people who keep posting that “Catholics worship Mary...Catholics worship statues.” You can show them fifty Catholic catechisms from the last 500 years, all of them condemning idolatry, and they just keep posting “Catholics worship Mary...Catholics worship statues.”
When a person argues against Catholicism with bald misstatements of what Catholics believe, all he accomplishes is to proclaim his own intellectual dishonesty.
