Stay at the lower levels of religion - do not be ambitious for promotion in terms of power in your local religious institution - and you do not have to encounter those who worship the DEVIL, at the top.

Yes, I know that looks like an almost insurmountable problem...let me take VATICAN politics as an example...how do the Catholic masses take on a demonically programmed POPE?
