'Black Theology' is, in my opinion, completely incompatible with the Gospel. The Holy Scriptures make it abundantly clear that in Christ, there "is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female" for we are all one in Him.(Gal 3:28) Rather than promoting separation, or highlighting our cultural differences, the Church unconditionally unites us, as one body. Not on the condition of race, or ethnicity; but on the basis of our humanity. He forms us out of nothing, granting us 'the breath of life' (Gen 2:7) and from our potentiality we are able to flourish culturally and socially. This diversity however, is a secondary issue - with culture, ethnicity, and background being gifts that should be shared, cherished, respected and appreciated; as opposed to an excuse for division and separation.
Theology, therefore, as a study of God, as an experience of God, and as a constant search for, and witness to His presence should not be divided by race, ethnicity or culture. It would be absurd to contemplate the idea of dividing Christian Theology, as a universal, unifying search for the knowledge and experience of our Creator and Almighty God.
How do we then tackle issues of oppression, race, and ethnicity? Rachel Dolezal is recently known for lying about her race (claiming to be African American when born to white parents) in order to prove a point. For one to sympathise with, act compassionately towards, and understand the problems and issues of oppressed and marginalised members of society, does not require ones own personal change, from white to black, from male to female, from heterosexual to homosexual. Every human being is given the divine gift, and calling, to place themselves in the others position; taking on our fellow human beings problems and making them our own. Oppression, disease, violence and trauma are unfortunate realities of humanity, which can be understood and tackled by all of humanity; not only certain groups.
I am certain that if we were to ask several African, South-American or Asian Theologians following the Christian faith, about so-called 'black theology' or 'white theology' they would deem it as absurd. Though there are diverse practices (e.g in African Orthodox Churches) the unity of the Faith, and the communion of the Holy Spirit is abundantly clear, and should not be taught, or thought of otherwise.
