Is it possible to reach a consensus on man's law?

Good question. Well, since men make man's law I don't think it's possible to reach a consensus here. Political process determines the law.
As far as God's Law is concerned, the believers claim that it's absolute, it exists independently from men, it's revealed, not made. That's why I asked whether it's possible for all to agree on what it is. Regards.

Well, we'll leave the theology for another day. Just wanted to make a brief point that secularists rarely turn their "skepticism" on themselves.

Something in the Bible about a speck and a mote in one's eye...anyway.

Cheers...HV
