I do not accept the Bible as the inspired, error-free, revealed word of God. I have never been baptized, and do not believe that the rite is necessary for salvation. And I do not believe in the Holy Trinity, nor that Jesus Christ is the son of God. Hell, I don't even believe in God.
But I am a proud Catholic nonetheless, much the same way that state Senators Rodney Tom and Tim Sheldon proclaim themselves "proud Democrats."
