Without wanting to get into the ethics of the thing, there is a little thing called 'Tradition' involved here. I don't see that observing old tradition for the sake of others as 'mocking' others beliefs, quite the opposite. I was married in Church because my Wife is a Christian and at the time I was just an unbeliever without conviction (now a comfortable Atheist). We have not had any of our 3 Children confirmed because that is their decision. Now, we would have a choice to be married in almost any setting without a member of the Clergy present but back then, it was Church or registry office. Considering that you pay for the services of the Vicar, Organist, Flower arrangements and the Civil service, I see the Church as a Business, offering it's Traditional style wedding service for sale. In the same way as you can have Elvis marry you in Vegas. If the Church doesn't like this, they can limit marriage services to regular members of their congregation.I don't make a point of mocking someone's faith. My children are not Christened, because I believe it to be their choice and also, because I will not go into a Church and promise to do things such as "bring the child up in the Christian faith" and so on, because I wouldn't and I don't go to Church, so that would be mocking the beliefs of Christians, in their own Church. Also the reason why I refused to be a God Parent to my best mates child (also a non Church goer). Incidentally, regarding that mate. They had to get confirmed etc, so that SHE could get married in a Church and when they got married, I stood at the front with them, knowing full well that she was pregnant.
So who is more at fault? Me, who lives as best he can and lets people believe what they want, and respects their belief enough to refuse my best mates request, or the couple who don't go to Church, getting confirmed, getting married while she was (secretly) pregnant, then promising to bring the child up as Christian, when we know full well that they won't, just because it is the done thing and or to please her Mother?
Now before any Christians get all righteous on me about this; I don't mean to disrespect you and I know that the Hallowed walls of the Church mean much more to you than that. I appreciate and respect that as I respect your beliefs but the Church is just beautiful bricks and mortar to me and with the Congregation falling year on year, my money will help in it's upkeep just the same as yours.
