Even about divorce and remarriage?
So far as I know, yes, but truthfully, I don’t know what the Copts think. I have attended the second marriage of an Ethiopian woman, her first marriage having ended in divorce, but that was in a Russian parish. The rules about divorce and remarriage go back to around the 8th century. Both in Constantinople and Rome, the patriarchates had to deal with marriage being a civil/state matter and the emperors and lower nobilyty having multiple marriages. Rome, interestingly enough, was the patriarchate most willing to cut the nobilty some slack back in those days, though as we know, that changed.
