Everyone has different reasons, I suppose. For instance, I once met a fellow who said the photos taken in church come out beautiful.
And why did you have a church wedding?
The moment I came to grasp the importance of the sacrament, my wife and I tried to arrange it as soon as possible, so that in case our earthly journey suddenly came to an end, we'd be together in eternity. For the same reason newborns are baptized — that, I believe, is very important.
Isn't it enough just to make a vow, without taking part in the sacrament?
That's roughly like standing in your own home declaring you'll thrash the hooligan who's shouting out in the street right now — even if you really would thrash him. Are you sure you'll do it, do you trust yourself? Peter trusted himself too, and yet he denied Christ. You have to do it properly, with a real desire to do such things, without lying to yourself — that matters.
Well, isn't the registry office enough?
The very moment the question of “enough” comes up, it's better not to have a church wedding at all. When marriage becomes a question of a trade-off, of confirming your intentions, then it's better not to enter into such a marriage in the first place.
Does life change at all after a church wedding?
Your earthly life, not a bit — except that more often you gaze silently into your wife's eyes and realize that one day you'll be waiting for her, and you'll surely wait until she comes!!!
