Who are you that judge another man's servant? to his own master he stands or falls. Yea, he shall be held up: for God is able to make him stand.
All Commentaries on Romans 14:4 Go To Romans 14
John Chrysostom
AD 407
It is not because someone does things which are worthy of escaping judgment that we are not to judge, but because the person in question is another man’s servant—not ours but God’s. It is up to God to decide what to do.
