Just curious--do you actually believe the religion or just practice it as a cultural thing to go along with the rest of your friends/family? I'm not trying to be intrusive or anything--just curious because you label yourself as "culturally" Catholic.
I'm agnostic, really. I lost my faith when I was in the Middle East and exposed to other religions. It seemed absurd that mine or any other had a unique claim to truth and it began to seem likely that religion is a probably a universal product of the human psyche. However, I had a good experience being brought up in the Catholic church and never lost my affection or respect for its teaching, traditions and rituals - and for the art it has inspired, especially perhaps musical.
When our son was born, my (French) wife and I discussed whether to bring him up with Catholicism or without and decided on the whole it was better to bring him up with it. That way, at least, he would understand Christianity when so many people nowadays don't, and he would thereby understand the roots of European culture and have full access to its artistic heritage. (As an American, you may not fully appreciate how much history is all around us in Europe.) So we started taking him to church. I joined the choir and got quite involved with it. I joined another choir when we moved to the Netherlands and we used to go to the sung Latin mass, since I didn't understand Dutch. Then my wife got cancer, and being aware her time was limited, it became rather calming to feel a sense of solidarity with the humanity of Christendom in past centuries, which we got from the ceremony and thousand year old plainchant of the Latin mass.
I find attending mass on Sunday and listening to the gospel, and often (not always
) the sermon, always teaches me or reminds me of something helpful about how to live my life. It provides a point in the week to stand back a bit, regain a sense of proportion and spend an hour in another, more timeless, world. I meet a quite different cross-section of the community from my daily comfortable middle-class bubble. And I enjoy the singing.
So there you have it. I suspect my reasons for religious observance are not far from those of very many people, actually. If you are not brought up with it, these reasons may seem inadequate, but there we are.
As it happens, my son has decided he doesn't believe in it and has stopped coming to church now. But he wants to study history at university, as his grandfather did. And he can look at a painting, or the frieze above a church door, or listen to a piece of religious music, and understand what it portrays.
