Actually it is recognizing that Jesus is the Lord (1Cor.12:3).
There are many gods and lords (1Cor.8:5) who are in fact, themselves fallen Angels and Satan himself (2Cor.4:4).
Modern versions remove the from 1Cor.12:3, thus anyone can now say Jesus is Lord without saying He is the Lord (King of Kings, Lord of Lords).
Wow. Anything to deflect the singular, personal, specific Lordship of Jesus Christ alone.
Another reason to stick with the KJV.
