how to transform a minor trespass into a major sin

Screwtape shows [Wormwood] [how to transform a minor trespass into a major sin]: Success here depends on confusing him. If you try to make him explicitly and professedly proud of being a Christian,you will probably fail; the Enemy’s warnings are too well known. If, on the other hand,you let [the idea of ‘we Christians’] [drop out altogether and merely make him complacent about ‘his set’],you will produce not true spiritual pride but mere social vanity //which, by comparison, is a trumpery, puny little sin.  * complacent ; 마음에 흡족한, 자기 만족의 [What you want] is [to keep a sly self-congratulation /mixing with all his thoughtsand never allow him to raise the question ‘What, precisely, am I congratulating myself about?’  [The idea of belonging to an inner ring, of being in a secret,] is very sweet to him.  Play on [that nerve].  Teach [him], using the influence of this girl /when she is silliest,[to adopt an air of amusement /at the things () the unbelievers say].  [Some theories //which he may meet /in modern Christian circles] may here prove helpful;theories, I mean, that place [the hope of society] /in some inner ring of ‘clerks’, some trained minority of theocrats.  It is no affair of yours [whether those theories are true or false];the great thing is to make Christianity a mystery religion //in which he feels himself [one of the initiates].
