Black Christianity is a spiritual adjustment that Africans made in order to unify; so as to overcome the social/physical/mental/spiritual discomfort. I believe our demise came as a result of our disunity.
I believe Dr. Iyanla Vanzant said it best when she said that we adjust to the level of deficiency that is around us.
I say that because the more we open our eyes, the less comfortable we are with our current leading spiritual system.
Black Christianity itself is going to have to adjust to the comfort level of blacks.
