With the heart a man believes unto justice, and with the mouth profession of faith is made unto salvation. For the Scripture says, Whoever believes in Him shall not be disappointed. For there is no distinction between Jew and Greek, for there is the same Lord of all, rich toward all who call upon Him. For whoever calls upon the name of the Lord shall be saved. How then are they to call upon him in Whom they have not believed? But how are they to believe Him Whom they have not heard? And how are they to hear, if no one preaches? And how are men to preach unless they be sent? As it is written, How beautiful are the feet of those who preach the Gospel of peace; of those who bring glad tidings of good things! But all did not obey the Gospel. For Isaiah says, Lord, who has believed our report? Faith, then, depends on hearing, and hearing on the word of Christ. But I say: Have they not heard? Yes, indeed, Their voice has gone forth into all the earth, and their words unto the ends of the world.
