It seems that pagans are always telling us not to judge based on one fragment of Scripture.
We are instructed to judge other Christians and how to do so.
We are given courts as an instrument of common grace so that all may receive judgment.
Liberals who throw this out ALWAYS forget the "go and sin no more" part.
Jesus did not pat the adulteress on the head and say: "poor dear, those meanies are sinners, too. Keep on committing adultery."
