The 9:00 adult Sunday school hour at my church wants to be expert-led and intellectual. I put participants in charge and asked them what they wanted.
The high school youth group wants to be a laid back routine of checking in, playing, and talking. I scheduled service projects.

Maybe discipleship is a constellation of invitations to join distinct communities performing diverse works. Maybe there’s no single community doing it all.
