Why have we lost, or neglected, the ability to disciple the mind for Christ?
In part, it may be that we have confused the need for a childlike faith (that is, an attitude of profound trust in God, and a faithful love for Him) with childish thinking. The apostle Paul, for one, had no confusion on this point. Reading any one of his epistles will show you that. And even Peter – the everyday workman, the fisherman – was no intellectual slouch, judging by his writings. What we have, everywhere in scripture, are profoundly intelligent teachings poured out from minds that are also inspired and centered in a love for God.
Step one generation away from the New Testament writers to meet the men who were discipled by the apostles and you will find treatises, apologies, and circular letters of stunning intelligence from those intensely devoted Church fathers.
Faith and a disciplined mental life were not natural enemies then. A well-informed mind held a place of honor. And it was believed that the Christian mind could be the best mind.
