Omnis enim, quicúmque invocáverit nomen Dómini, salvus erit. Quómodo ergo invocábunt, in quem non credidérunt? Aut quómodo credent ei, quem non audiérunt? Quómodo autem áudient sine prædicánte? Quómodo vero prædicábunt, nisi mittántur? sicut scriptum est: «Quam speciósi pedes evangelizántium pacem, evangelizántium bona!»

For whosoever shall call upon the name of the Lord, shall be saved. How then shall they call on him, in whom they have not believed? Or how shall they believe him, of whom they have not heard? And how shall they hear, without a preacher? And how shall they preach unless they be sent, as it is written: “How beautiful are the feet of them that preach the gospel of peace, of them that bring glad tidings of good things!”

- Rom. X, 13-15
