Iโm shocked the gospel would be described as โmilkโ and not โmeat!โ
I would think milk vs. meat has more to do with how deep into a subject you go rather than the subject itself. Even something โeveryone knowsโ has depth and opportunity for study. And especially things that โeveryone knowsโ need to be revisited to be clear theyโre really understood.
Besides, you have no idea when someone will be attending for the first time, or even thinking seriously about an issue for the first time. Not to mention children attending the church.
