Matthew 7:15 King James Version (KJV)

15 Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.




The center of Christianity flows from the Word of God, in exactly the same way the center of Judaism did.

You cannot pick and choose which part of the Gospel to believe, or to make a false determination that one part of the Word contradicts another - that is Heresy.
