So if open sodomy and fornication are not cause for shunning, where is the line drawn today among open minded Christians?
Sex on the living room floor in front of everybody? Offering everyone an after-dinner sharing of the bong? Having a sexual relation with your sibling? Abandonment of family to take up a life of pole-dancing and cocaine flings? Making a living as a hitman? Practicing "medicine" as an abortionist? Keeping workers at your business penned in like slaves? Beating your children and wife?
Surely there must be somethings which are still beyond the pale, and not an "opportunity to witness".
Did Christ have any association with sinners?
