A new mishnah! A blasphemer is only culpable once he mentions the Name of God. All testimony would be provided using a euphemism, until the very end, when one occasion of direct citation of the blasphemy would take place before any judgement would be brought into effect. The judges who heard this would tear their garments for this desecration. Also, the 7 Noachide laws, and dispute over what they are. That is, the sages had other laws to add - several of which were connected to false approaches to the Divine or witchcraft, but even grafting was recommended for the list, though they weren't included, in the long run. Plus, a discussion on the nature of civil law, and why it is one of the 7 (except for the view that says it doesn't belong there, and "sterilization and grafting/kilayim" were substituted instead).
