I became Catholic because God’s grace pushed me there despite myself.
I was raised Protestant but, after coming to college, started privately considering myself an agnostic. This wasn’t so much out of any intellectual doubts (though I did try to force them on myself early on) as it was out of a stubborn desire to sin. After living like this fairly consistently for about three semesters, a neutral, off-hand comment from a professor about Catholicism sparked something within me - or rather, God used that opportunity to spark something within me. The following summer (2011) I couldn’t find any sort of job or internship and all my friends were out of town, so for about the first month I ended spending almost all of my time contemplating Catholicism. On a certain level this made no sense; like I said, I was stubbornly refusing to repent of my sin and trying to deny God to do that. However, I was slowly beginning to feel how empty my life was. By the end of June I was all but set on converting. In early July I attended a seminar in Washington, D.C. (sort of a consolation price for being turned down for one internship); the seminar was all-expenses-paid, and where else did we stay but the Catholic University campus. This meant, for one thing, that I was surrounded day and night by Catholic things - crucifixes, etc; even more, it meant that I went to Mass for the first time ever at the National Shrine of the Immaculate Conception. One whiff of incense and I was hooked. :highprayer: By the Grace of God I was receive into full communion with the Church on Divine Mercy Sunday.
As others have mentioned, my conversion was very intellectual. On the one hand, I’m glad for this; I tend to trust me reason more than my emotion and, after all, who am I to question how God acts? On the other hand, it’s been something of a challenge. I grew up with the assumption that true conversion was necessarily an emotional, almost ecstatic experience, and I’d not really had anything like that (that I had not conjured up within myself), which led me into doubt and despair from time to time. Slowly, though, I’m learning to focus on action and will, rather than emotion and sentiment (cf. 1 John 3:19-20), particularly through St. Francis de Sales’ Introduction to the Devout Life.
St Francis de Sales, pray for us!
[Edit] As far as specific reasons, I eventually came to see that the Catholic Church is more faithful to Scripture than the Sola Scriptura types: John 6, John 20, 1 Cor. 11:29, Romans 11:22, 1 Timothy 3:14-15, and many, many others.
