Joeseph had a wife, who would've been called "his marry"…ergo, "Mary". Joeseph was Mary's Ba'al (husband)…the old Ball & Chain…bonds of matrimony…bondage…slavery.
The husband used to be "king" of his castle, until the Church revoked his soveringty and forced him to worship the King of the Realm..and his boss, Satan, under penalty of death.
