I'm a big fan of the local Church. And I'm a big fan of teaching. But have we mistaken Jesus' last commission, "Teach them to obey all that I have taught you', for the more neutered version "Teach them what I taught you"? Or even worse, the more reduced, mangled, & the most commonly practiced "Teach them what I've said."
I suspect that one of the differences between them is the difference between a great lecture on a sacred subject vs a great apprenticeship in that sacred subject. Ya know, the difference between an audience member & an apprentice.
Further, If you are commissioned to simply 'teach them what I've taught", that's one thing. But to teach them, & to teach them to "do" what you yourself have 1st learned to "do" - This is an entirely different thing, & likely instigating different models than the common one currently used over the last few centuries. To make sure we understood what Jesus meant, he begins this great commission with the words, "Make disciples..."
Making bigger audiences, or even making devoted church members is not the same goal, is it?
"Go make disciples, teaching them to obey all that I've taught you to obey,,," - Jesus
