While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled.
Act 1:25
That he may take part of this ministry and apostleship, from which Judas by transgression fell, that he might go to his own place.
Judas did both and got kicked out.
One cannot be kicked out of the BOC.
