i never had a rubric for why Jesus told some people to tell everyone they were healed and others not to tell. In the story of the healed man in Matt 8–the former leper, i now believe that He tells the man not to identify to anyone but the priest (in offering a sacrifice) because he was giving the man permission to be “normal.” Jesus is saying you are not an outcast anymore. You are complete.
After the experience of being treated as though we were contagious for two years because we had the temerity to tell our story openly, Jesus’ injunction seems more like a great grace than some ineluctible secrecy.
He is free. the man is free because he is completely healed. That is the only way Jesus rolls.
