When in Systematic Theology I @ TLS, I wrote a comment in my notebook, about looking further at Gudina Tumsa. Part of that would be to see how and whether a tension between NMS and NLM played out in the formation and the first years of the Mekane Yesus Church.
I don’t remember the reason for this comment but it might be worth examining further.
Gudina Tumsa, Ethiopia, Ethiopian Evangelical Church Mekane Yesus.
