'Person' in the Bible

For many deceivers have gone out into the world. They refuse to acknowledge Jesus the Messiah as having become human. Any such person is a deceiver and an antichrist.

Everyone who does not remain true to the teaching of the Messiah, but goes beyond it, does not have God. The person who remains true to the teaching of the Messiah has both the Father and the Son.

because the person who gives him a greeting shares in his evil deeds.
