“Since I will not accept the idea that a single verse (taken out of context, btw) is sufficient to build the unHoly Roman Empire upon”
Then you reject the verse two verses previous, “You are the Christ” also.
LOL! Is that the best you've got?
One MIGHT suggest that if a line of thinking is represented ONLY IN ONE VERSE, especially something as overweening and ponderous as the Roman church has designed, one might think it prudent to accept another interpretation.
