It’s a question of dominion. You and I are permitted to take assertive action only within the boundaries of covenant. When it comes to social and political issues, the prevailing applicable covenant is Noah’s. We could easily get lost hashing out the details of the Seven Noahic Laws, but those will not help us because there are prerequisites not stated. The primary issue is that God has wired us to live under Ancient Near Eastern (ANE) feudalism. Without that, you simply cannot have a valid covenant for human organization. Oh, and it requires you reject Western intellectual assumptions.
Inside a covenant community of faith, these changes are pretty easy. Noah’s Covenant isn’t that hard under a presumption of genuine faith. Granted, you could choose a simulacrum of Moses’ Law, so long as you realize that the ritual offerings are swept away by the Cross, aside from offerings given to support worship and leaders. However, it’s largely unnecessary to go that way and Noah is good enough. Instead, we use Moses to inform our understanding of Noah, as Moses has effectively ended, but Noah remains in force so long as there are rainbows. Still, God requires your church be organized like an ANE feudal household. Otherwise, it’s not really a covenant community. Mainstream Western churches are essentially corporations, not spiritual families. It can’t be both. You may well have the latter inside the former, but they aren’t the same body in moral terms because each stands in a different sphere, so you’ll satisfy the requirements for one or the other, but not both.
