What about John 6?
I mean, it’s clear that you reject Christ’s words when he says “Thou art Peter and upon this Rock I will build my church,” The reasons you reject Christ’s words can only be conjectured. But he did say, in Matthew 7, that you would be judged by the same measure you use to judge. Once again, it’s conjecture as to why...that’s also Scripture. Now, if you think all your past, presnt and future sins are covered, what about that judgement? Do you think you are immune to it? That’s not what Scripture says.
It makes me wonder, sometimes, why protestants who literally scream online about the authority of Scripture reject it. Not only these two, but Hebrews 13. Do you also reject that?
Read that entire passage. The Rock is referring back to God who is the ONLY rock as evidenced in many passages of scripture.
