Yes, that is an explicit one, that verse. Clear as day. All Bible-believing Christians need to accept that verse, too.

I can't believe I've never seen that one used as a defense of Catholicism. God bless, that's based.
In my experience people always jump to saying that Catholics misunderstand the "...on this rock," verse.
Yeah, but even then it makes more sense to go to a mainline protestant church that has the traditions and institution. Unity is very important to the church, and being non-denominational seems like an unjustified schism (not that other schisms were necessarily justified).
