In my experience as an observant Catholic, the idea that God is everywhere is not enough for most of the congregation. They need something to grasp onto. An event, an icon, an outlet, if you may. Like that Feast of the Black Nazarene thingee. The more hardcore, the more fulfilling for some.
Me? I find God in the most unexpected places, both literally and figuratively.
Oh, and Jesus too.
