Donal has a good post up on The high ground right now with some good comments too. Check it out.
Mostly, it all goes back to the roles and responsibilities of Christians to themselves and Christian to non-Christians.
Matthew 5:13 “You are the salt of the earth; but if the salt has become tasteless, how [e]can it be made salty again? It is no longer good for anything, except to be thrown out and trampled under foot by men.
14 “You are the light of the world. A city set on a [f]hill cannot be hidden; 15 nor does anyone light a lamp and put it under a [g]basket, but on the lampstand, and it gives light to all who are in the house. 16 Let your light shine before men in such a way that they may see your good works, and glorify your Father who is in heaven.
1 Cor 5:12 For what have I to do with judging outsiders? Is it not those inside the church whom you are to judge?
Christians have a long history of not policing themselves as much as they should and try to police the world too much. If you’ve read the Nashville statements and the follow ups, it’s basically attempting to negate any semblance of LGBT infecting “marriage.” However, we know that even if people claim LGBT marriages exist, they do not exist to God. Our primary duty is to set an example of how good marriage is to be salt and light to those who support pagan marriages.
The Church should be focusing on the roles and responsibilities of men and women in marriage — headship-submission, love-respect, no sexual denial by either spouse, etc. — and fixing the disastrous divorce rates among ‘Christians.’ As long as “Christian marriages” look the same as the world in their marriages, they are not salt or light at all.
