I consistently have both spiritual and intellectual conversions.
I’m not sure that I have much of a story, but everyone has some sort of intellectual objections to Catholicism. Mine were largely standard atheistic arguments. Over time, I eventually began to see that there were answers to many of my questions and objections, and I began to investigate them.
Frankly, my intellectual objections were in some way sincere, but they were mostly rationalizations to excuse myself and my behavior. I wanted to do what I was doing, and the idea of certain realities being more than mere religious nonsense was very inconvenient.
But the spiritual aspect was, for me, more than just “feeling at home.” I’ve had three great lights given to me, and the first was to be able to perceive the spiritual effects of Baptism, while the second two were with regard to both Confession and the Holy Eucharist. Those lights were tremendous graces.
Actually, perhaps there’s at least a fourth light: the great awareness of how utterly miserable and pointless life was before Jesus. I had a lot going for me on the external level, but I was full of confusion inside. Finding “the truth” on any subject you can imagine seemed like one big exercise in futility. I wandered about aimlessly.
All of this ties in with the intellectual level because, once I found my world-view being formed by the Church, I’ve noticed how all-encompassing the world-view happens to be. I think I’m a more consistent thinker with a better means of analyzing reality than I ever was before.
