You folks who are at present Bible believers will be able to look this up, a servant of a heathen king was talking to a prophet of Israel, he was concerned that he helped his blind master bow down to an idol daily, The Israelite prophet told the servant to "go in peace" interpreted to meaning: in some circumstances don't worry about it,
So even under strict law there were exceptions to a rule,
In practical terms today, men come into these situations with their minds already made up,
I've already noticed that when normal people are faced with such a situation, they'll say in effect, "I may or may not agree with what you're doing but I'm not going to judge you, you're my friend, you need my help and I'm here for you :0)
