72 But in this battle joined by the powers of darkness against the very idea of Divinity, it is Our fond hope that, besides the host which glories in the name of Christ, all those - and they comprise the overwhelming majority of mankind, - who still believe in God and pay Him homage may take a decisive part. We therefore renew the invitation extended to them five years ago in Our Encyclical Caritate Christi , invoking their loyal and hearty collaboration "in order to ward off from mankind the great danger that threatens all alike." Since, as We then said, "belief in God is the unshakable foundation of all social order and of all responsibility on earth, it follows that all those who do not want anarchy and terrorism ought to take energetic steps to prevent the enemies of religion from attaining the goal they have so brazenly proclaimed to the world."
