Ain't life grand? Hows things? You mentioned that you had moved and are looking for work. I hope things work out for you. This is a terrible time to be looking with layoffs and cutbacks being quite the norm nowadays.
Other than the obvious, pretty good.
As for Mt. 16:18, Jesus promised that he would build his church on the rock (Peter) and the gates of hell would not prevail (to have power over, overpower, prevail against ). From this the Catholics assert that Jesus promised perfect doctrine to his church. I do not see that promise, especially in this verse. I see the promise that God's people will not be overtaken by the gates of hell. I'm not sure how that translates into perfect doctrine or still more, how it only applies to the RCC.
The Kingdom of God is not the RCC, nor is it even the church. It is the rule and reign of God (scroll down to definition III). When you assert that the Kingdom of God is equal to the church, you have a fundamentally lacking view of what the Kingdom of God is. The view that the Kingdom of God is the church just does not fit with the full range (esp. of the Gospels) of statements concerning the Kingdom.
