“I never understand anti-Semitic Christians, or people that call themselves “Christians”.”
John 8:44, lying is his native tongue they are just representing their father.
[44] You are of your father the devil, and the desires of your father you will do. He was a murderer from the beginning, and he stood not in the truth; because truth is not in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father thereof. [45] But if I say the truth, you believe me not.
