Commentators agree that this verse establishes a core Christian ethic: love for a fellow believer should take precedence over our personal freedoms. Paul argues it is "good" or "noble" to voluntarily abstain from things you have a right to enjoy (like certain foods or wine) if exercising that right would cause another Christian to sin against their conscience or have their faith shaken. This is an act of self-denial for the sake of another's spiritual health.
