I'm afraid I don't understand. Religion teaches us that we should love and have a family, (not like I'm saying you have to, but y'know, that's what he'd like) and so marriage is a sacrament. Religion and love are closely related. Marriage has always been religious, and though it may not be now, people still do it as just... a nice thing to show someone's love. I'm sounding really fruity. If you feel so strongly you should just not get married, go fear that your wife will be hit on every time you're out.
You really don't have to be married to make a statement.
That's an extremely generalized statement. ALL marriage is religious, in ALL cultures? Religion in ALL cultures tells us we should love and have a family?
You can't just take your experiences with Christianity and apply it to all other religions. Marriage isn't necessarily a religious thing.
