The question about redefining marriage is an incredibly significant policy decision for our society. It may seem minor to many, but I think it is symbolic of bigger things. And if the basis for our decision-making is change by intimidation, whether by forceful overpowering or emotional manipulation, I don't think it bodes well for a healthy and civil community. Our society has benefited from a Christian heritage that sees humility, respect, compassion and love of all--despite disagreement, even opposition--as virtues. And yes, it is sad that we Christians don't always live up to those standards either, sometimes avoiding healthy conflict, sometimes enabling bad behaviours. But the more we undermine Christianity, and encourage "victory by powerful assertion", the more we can expect real civility to also disappear. It won't be a healthy community. And it won't be a good side of history to be on.
May Jesus help us to live the way he showed us: "So Jesus called them together and said, 'You know that the rulers in this world lord it over their people, and officials flaunt their authority over those under them. But among you it will be different. Whoever wants to be a leader among you must be your servant, and whoever wants to be first among you must be the slave of everyone else. For even the Son of Man came not to be served but to serve others and to give his life as a ransom for many.'" (Mark 10:42-45, NLT).
