Yeah that's just too vague to really mean anything. They wanted to fix something in 5e that wasn't broken. Why create a large pantheon that unquestionably exists and influences mortals just to downplay them when Paladins' use of Divine Magic is concerned? The Oaths should at least be fleshed out MUCH more. Who wrote them down? Who do you swear them to? Which gods oversee said tenets? They are so structured there should clearly be an Order. Or did you find a shopping list of tenets on a piece of paper somewhere and swore it to the wind?
