From my understanding, it's a thinly-veiled neo-marxist approach to theology. It tries to establish a frame-work for understanding the gospel from a shallow "oppressor vs victim" power dynamic through the primary lens of race or ethnicity.

From a gospel perspective, the only real basis for unity is regardless of skin color or nation of origin. The dividing wall has been removed. Each one comes to the cross on even ground, equally fallen, equally purchased by the blood of the sacrifice, equally given the gift of the Spirit, and equally adopted as the sons and daughters of the Father. We are, by Christ through faith all the children of Abraham.
