Our traddiest readers will probably already be aware of the recent radio talk given by the Elderly Gentleman from Argentina, concerning the relationship of disobedience (and "cling[ing] to what has always been done") to idolatry and divination. One might be tempted to consider this yet another example of the modernist's misuse of scripture and doctrine to support whatever program is needing to be pushed.

Clericalism is alive and well, and when clergy start accusing those who aren't following their every personal rule of witchcraft and idolatry, it might be because they feel the walls closing in.
