If this episode is what it appears to be, it is an absolute outrage. I could possibly understand if Rev. Nduka had publicly staged a confrontation, but this was done privately through e-mail. Unless there is some sort of restriction within the Anglican Communion against clergy questioning the views or actions of their bishops (and granted I am Catholic so I don't really have any idea), this seems petty and vindictive. I have spoken with clergymen from many denominations (Catholic, Anglican, Lutheran, Presbyterian and Methodist) who all agree Africa is where many if not all of the great Christian leaders and theologians are now coming from. What was done to Nduka is immoral and cruel by any standard and it is even more outrageous because he was privately trying to point out that his superior was condoning a life of sin.
I seem to recall another great Christian leader/theologian who lived in a place called Hippo in North Africa.
