I'd claim that twas intellect that lead me to Catholicism but the truth is more mundane. I was born into it. A gift I don't deserve. That makes me concerned that I am just out here happily confirming my biases like everyone else. How lucky for me to be born into the right religion!!

But when I hit the questioning age I decided that sticking with it till falsified made more sense than dropping it till proven. After all my ancestors successfully reproduced and lived good lives.

The thing that got my attention, was that every time I asked my own questions, and did the painful leg work to really figure out for myself some obscure corner of morality or philosophy, it turned out that the church had already come to my hard fought conclusions millenia ago and had better reasoning for it. Every. Darn. Time.

When a source of information has a 100% track-record (I am talking beliefs taught not necessarily the actions of adherents) you don't stop questioning for yourself, but you also just go with what they say for the things you haven't had time or ability to tackle yourself. Having a look-up table for how to handle obscure situations in a complex world is a superpower.

There's more to it than that but it's kinda were I start post parental indoctrination.
