The intention, laid out for us in Scripture, is for the institutional Church to receive the apostles, their emissaries, and their letters. When we get their letters, we in the Church are supposed to open them up and do what they say. Unfortunately, Diotrephes has an online discipleship training program, and his imitators are everywhere. Moreover, his imitators and heirs are, just like he was, entrenched in the Church.
