In Book V of his Confessions, St Augustine describes a period when his trust in the Manichaean religion was ebbing, and his skepticism was growing. He was not yet willing, however, to return to the catholic faith his mother had entrusted him to, the faith he had left at university. He writes,
When my mind attempted to return to the Catholic faith, it was rebuffed because the Catholic faith is not what I thought.Confessions V.x (20)
Eventually, he would go to Milan and encounter Ambrose. Through Ambrose’s preaching, he slowly learned better what the Catholic faith really was, and then leave Manichaeism, and then, after some time amongst the Platonists, eventually fully convert to catholic, orthodox Christianity and get baptised.
How many people — even those entrusted to the church by their parents, raised in our Sunday schools and youth groups — leave in high school and university, and sometimes might feel a tug to return to the faith of their youth? But they don’t return to the faith. And sometimes, when you look at deconversion and deconstruction stories of their faith, you realise that the Christian faith they rejected is not actually true, sound orthodoxy, but a misconception and false projection.
This is why good Christian education is a component of discipleship to Jesus — simply so that we can understand our Lord and His world better, and thus more easily submit ourselves to His Lordship, His teaching, and His worship.
