I think we should call the leaders of such Sunday Meetup groups "Priests", or maybe "Ministers".
The ones you mentioned do not meet to talk about ancient philosophy. They meet to talk about an imaginary entity you come to kneel to and pray it does not bring the end of the world.
The managers of these groups also expect the participants to tell them what they did wrong (confession) and when they hear that a guy is going to rape someone because he feels that need, they cowardly cover for him. Mostly because they put their comfort above the life of someone else (secret of confession).
So yeah, that wood be good but for now this is just a meeting of people who learned this from their parents and do not want to think about the whole craziness of the idea.
The charity work is nice, though.
(And I think the answer is no, the Buddha did not say that.)
