Taking the Lord's name in Vain in the NT: Where does it say not to take the Lord's name in Vain in the New Testament? Sabbath Commandment in the NT: So you just admitted that the taking the Lord's name in vain commandment is not found in the NT, but that we still have to obey it, but then say the Sabbath commandment isn't found in the NT, but we still have to keep it, just like not taking the Lord's name in vain isn't, but still obey that. [Matthew 24:20]
