People who believe in Christ are bretheren, because they have the same father.
People who do not believe, are not bretheren, cos they do not have the father.

"Christian" means "like Christ" = like Jesus.
Satan is the accuser of the bretheren. He is not a friend. Satan thinks that he is better than God.

Culture is leaven. Jesus is the unleavened bread.
That's why a Cult is called a Cult. "Cultural Unity" is not holy, it is ANTI-God. "Anti" does not mean against, it means "replace".

God is above all cultures and race ideologies!
