"When one has become engaged to a girl, but has in addition deflowered her sister too, so that she has been made pregnant by him, and he has after this married the one betrothed to him, but the one deflowered has hanged herself. Those aware of the facts have been ordered to spend ten years as co-standers in order to gain admission, in accordance with the fixed degrees."
-Canon 25, Council at Ancyra 314
