"But false prophets also appeared among the people, just as there will also be false teachers among you, who will secretly introduce destructive heresies, even denying the Master(Jesus) who bought them, bringing swift destruction upon themselves."
2 Peter 2:1
“ Sin of the priests
"A son honors his father, and a servant his master. Then if I am a father, where is My honor? And if I am a master, where is My respect?’ says the Lord of armies to you, the priests who despise My name! But you say, ‘How have we despised Your name?’ You are presenting defiled food (spiritualfood) upon My altar. But you say, ‘How have we defiled You?’ In that you say, ‘The table of the Lord is to be despised.’ “But you are profaning it by your saying, ‘The table of the Lord is defiled, and as for its fruit, its food is to be despised.’ You also say, ‘See, how tiresome it is!’ And you view it as trivial,” says the Lord of armies, “and you bring what was taken by robbery and what is lame or sick; so you bring the offering! Should I accept it from your hand?” says the Lord."
Malachi 1:6-7, 12-13
