You're proof texting one verse from the Old Testament to prove your case.
And to think you will criticize a RC for proof texting a single verse of Scripture to "prove" Peter was the Rock. ;-)
See the post from Invincibly Ignorant. Better yet, read the verses of Isaiah 7 which follow your "magic" verse.
What got all this started???? I Amen Dave for saying Mary was a virgin, and suddenly you put me in the Catholic Camp. Who are you to criticize me???
