143. 'And who have not known the depths of Satan, as they say' signifies who do not understand the interiors of those things, which are totally untrue. That by 'Satan' is understood the hell [formed] out of those who are in untruths, and abstractly the untruths, may be seen above (n. 97). Consequently by its 'depths' are signified the interiors of the doctrine separated from charity, and these are totally untrue. The depths and interiors of that doctrine are the things that are given out in their books, also in lectures in the colleges, and thence in preachings. Of what quality these are may be seen in the things premised to Chapter 1, where their Doctrinal Tenets have been quoted, particularly there [the section treating] of JUSTIFICATION BY FAITH, and OF GOOD WORKS. There it may be seen stated that only the clergy are acquainted with the mysteries of that doctrine, but not the laity, and therefore chiefly the latter are understood by those 'who have not known the depths'.
