There are also quite a few illogical and weakly-supported Catholic “theologians” defending your faith. Do they define Catholic theology? Could we not equally say some Catholic theology is weak, liberal, and poorly contrived?
I don't think that it follows that a theology is only as strong as its weakest advocate. First, Catholic theology is very much defined and falls within a tradition and a given structure. As does Calvinism, Anglicanism, Lutheranism, etc. A weak theologian simply does not add to the well. Second, I never said Protestant theologians are shallow - I said the theology is shallow.
“Purpose Driven” Protestantism isn’t a denomination of Protestantism. I don’t know any Warrenians — though I do know several people that read the book. A couple are Baptists, a couple are Methodists, and one is non-denominational Protestant. None are shallow Christians.
I've read his book. I've checked out the What We Believe section of his church's website. A Christian group with a set of beliefs *is* a Christian denomination. Now, it isn't Methodist, Calvinist, Lutheran, Anglican, Baptist...but it has to be something. Whatever his denomination is, as expounded by his book, has a shallow theology. Again, I've never claimed he was a shallow person, or a shallow Christian, or any such ad hominem.
Do you think a Purpose Driven Life is meant to be a tome of theology? Do you think a "what we believe" section of a church website is meant to represent every facet of a church's theology? Do you think there is any reason why there should be a set of basic principles listed by a church before going into church doctrine and deeper theological issues?
Maybe you believe that before someone sets foot in a church, they should read the enire Bible, and throw in a couple of commentaries on each passage while you're at it?
