Screwtape (C.S. Lewis’ demonic character) shows real ingenuity in his approach to tripping up Christians.
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. What you want is to keep a sly self-congratulation mixing with all his thoughts and 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.
Of course, the “him” to which Screwtape refers is Wormwood’s personal project, an unsuspecting Christian. Lewis appears to grant him greater discernment than is typically true; I’ve known many “Christians” who displayed pride in their religious affiliation because they either don’t know, or care about, the Bible’s warnings about vain pride.
“Spiritual pride” is an oxymoron. Whenever a Christian takes a, “big I, little you,” perspective based on his position in Christ, chances are he’s not “in Christ” at all. That includes making snarky, patronizing comments to or about atheists or homosexuals, regardless how snarky or patronizing they are.
How easily we forget that the only damnable sin is that of rejecting Jesus’ offer of forgiveness for our sins and reconciliation with the Father. Think of such rejection as a refusal to pray as King David did in Psalm 139:23-24 “Search me, O God, and know my heart! Try me and know my thoughts! And see if there be any grievous way in me, and lead me in the way everlasting!” What is “the way everlasting?” Well, its map is God’s complete Word, and it’s called, “the gospel of Jesus Christ.” Unlike GPS, or Screwtape, it won’t mislead you.
