I already posted previously the relevant Early Church Fathers Comentary from Catena Aurea but such things just end-up being ignored by you.
Here is your brother Baptist D.A. Carson.... The underlying Aramaic is in thios case unquestionable; at most probably Kepha was usd in both clauses (You are kepha and on this Kepha) since the word was used both for a name and for a "rock." The Peshitta (written in Syriac, a language cognate with a dialect pf Aramaic) makes no distinction between the words in the two clauses
IOW< no matte how many times you assert optherwise, it is both that Kepha is kepha AND Kepha's Confession...
I am entitled to disagree with Carson.
Jesus didn't say both. It wasn't a plural. The "this Rock" either applies to Peter or Peter's confession. Not both.
I do not take my orders from Man. I take them from Scripture - as Scripture says I should.
