What do you expect from D&D?

[Jeff the Green]

Since it's not explicitly called out as a code of conduct, it has no effect as per RAW. That said, I would have no trouble with the DM issuing a cleric PC warnings via divine proxy if they cross a line or two or even stripping them of their powers if they don't learn after the first few chastising angels.

That has to be the flimsiest RAW argument I've seen in this forum in a while.

Yes, I'm aware of the context of this remark
