The falsehood of trinity

The Trinity cannot be one God in three persons and three gods in an office known as the Trinity, etc. These teachings are mutually exclusive

Most Christ-professing people believe God is an unfathomable MYSTERY; a "Trinity." This doctrine, proposed and accepted more than three hundred years after Christ, is held by the Roman Catholic church and dozens of Protestant denominations. Millions seem to accept it without question; singing songs like "Holy, Holy, Holy….Blessed Trinity," each Sunday.
