Why the Church?

Catholic Ragemonkey Fr. Hamilton recently posted about the difference between civil marriage and marriage in the Church. So my question to all of you out there, especially those who are married, is why did you, or will you, get married in the Church? From my experience as the wedding day approaches it is easiest just to say, "because that is what we are supposed to do." I hope that there is always more to it. What more is there?

For me I have to say it is this line from Ephesians (5:25): "Husbands, love your wives, even as Christ loved the church and handed himself over for her." If the Church will help me to love my wife in this way, how can I say no to that?
