As Jesus was about to leave His disciples, He prayed for them in a most touching, solemn manner that they all might be one “as Thou, Father, art in Me, and I in Thee, that they also may be one in Us: that the world may believe that Thou hast sent Me. And the glory which Thou gavest Me I have given them; that they may be one, even as We are one: I in them, and Thou in Me, that they may be made perfect in one; and that the world may know that Thou hast sent Me, and hast loved them, as Thou hast loved Me.” The apostle Paul in his first epistle to the Corinthians exhorts them to unity: “Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and that there be no divisions among you; but that ye be perfectly joined together in the same mind and in the same judgment.” {3T 446.2}

Da Jesus var ved at forlade sine disciple, bad han for dem på den mest rørende og højtidelige måde at de alle måtte være et »ligesom du, Fader! i mig og jeg i dig, at også de må være ét i os, så verden må tro, at du har sendt mig. Og den herlighed, du har givet mig, den har jeg givet dem, for at de skal være ét, ligesom vi er ét, jeg i dem og du i mig, for at de må være fuldkommen ét, så verden kan forstå, at du har sendt mig og har elsket dem, ligesom du har elsket mig.« Apostlen Paulus formaner i sit første brev til Korinterne dem til enhed: »Men jeg formaner jer, brødre, ved vor Herres Jesu Kristi navn, at I alle skal være enige indbyrdes og at der ikke må findes splittelser iblandt jer, men at I skal være fuldt ud forenede i samme sind og samme overbevisning."
