Chapter 23 of the Screwtape Letters finds the devil pivotingfrom outright temptation to something far more sophisticated: the corruption of faith from within. With the Patient now surrounded by good, intelligent Christians, Screwtape's strategy is twofold — first, to replace the living,personal Christ with a safely academic "Historical Jesus," ascholarly construction that can be studied and debated but never truly worshipped or encountered; and second, to gradually invert the relationship between faith and politics until Christianity becomes merely a vehicle for a socialagenda rather than a living relationship with God.
Drawing on Pope Benedict XVI's encyclical Deus CaritasEst and St. Josemaría's insistence on meeting Christ in the Eucharist and prayer, the episode argues that authentic Christianity is neither an ethical theory nor a political programme, but a personal encounter with a risen andliving person — and closes with a challenge to examine honestly whether our faith is shaping our convictions, or whether our convictions have quietly reshaped our faith.
