6 Jesus Christ, the Liberator of mankind, is the everlasting and ever flowing source of all the good things that come to us from the infinite bounty of God; so that He who has once saved the world is he who will save it throughout all ages; "for there is no other name under heaven given to men whereby We must be saved."(1) If then the human race fall into sin, either through its natural propensities or through the faults of men, it is absolutely indispensable to have recourse to Jesus Christ and to recognize in Him the most powerful and the most sure means of salvation. For so great and so efficacious is its divine virtue that it is at once a refuge from all dangers and a remedy for all evils. And the cure is certain, if mankind returns to the profession of Christian doctrine and to the rules of life laid down by the Gospel.
