What difference has it made now since a COG Ordained Bishop’s wife is now his equal rather than a helpmate? Can you tell the differences?
A COG ordained bishop is to be the husband of one wife. He can remarry if the first wife dies. The ordained bishop cannot remarry as long as she lives.

What does all this mean when it comes to ordaining women to be bishops? Shouldn’t it be opposed on Biblical grounds?
