who gets to judge what church is Christian? some would say a church itself is unchristian and against what Jesus said...so I could say all who go to church are not Christian.
Sure, which is why it's useful to look at what (a) the Bible says, and what (b) the vast majority of Christians agree Christianity is all about.
The vast majority say that it's about God's love for mankind, which is infinite and, moreover, universal. Anyone who accepts God is reborn into a spiritual nation of Israel, which by the very nature of its existence denies that there anymore literal nation of Israel -- that is, that there are no more chosen races. The universality of God's love is, to me, the central tenet of Christianity.
Black theology rejects this, with its conception of God as a destroying racial avenger out to save blacks only and destroy whites. Ergo it is a heresy and not Christian.
I can, if you like, provide relevant citations from Dr. Cone's Black Theology and Black Power, which Rev. Wright has endorsed unequivocally.
