19 To come back to what We said at the beginning, We turn affectionately to all Our children and conjure them in the name of Our Lord Jesus Christ to forget mutual differences and offences and draw together in the bonds of Christian charity, from which none are excluded and within which none are strangers. We fervently exhort all the nations, under the inspiration of Christian benevolence, to establish a true peace among themselves and join together in an alliance which shall be just and therefore lasting. And lastly We appeal to all men and all peoples to join in mind and heart with the Catholic Church and through the Church with Christ the Redeemer of the human race, so that we may address to them in very truth the words of St. Paul to the Ephesians: "But now in Christ Jesus you who sometimes were afar off, are made nigh by the blood of Christ. For He is our peace, Who hath made both one, and breaking down the middle wall of partition . . . killing the enmities in himself. And coming he preached peace to you that were afar off and peace to them that were nigh."
