It is interesting to me that those who use verses 13 through 20 as a basis to justify select authority do not use the same expansive interpretive technique in the directly following verses (21-23). If Peter was the first of the "true church leadership," is all the leadership satanic, too?

Nevermind the other reasons (like how binding and loosing is mentioned for a broader audience shortly thereafter, or that if it's the "true line" why people outside the line are needed to choose the next successor, etc.) This type of selective interpretation gets us in a lot of trouble, theologically.

Matthew 16:13, Matthew 16:14-22 and Matthew 16:23
