24 The society which Christ founded can be attacked, but not defeated, for she draws her strength from God, not from man. And yet, there is no doubt that she will be harassed through the centuries by persecutions, by contradictions, by calumnies - as was the lot long ago of her Divine Founder - for He said: "If they have persecuted me, they will persecute you also." But it is equally certain that, just as Christ our Redeemer rose in triumph, so the Church shall someday win a peaceful victory over all her enemies.
