2 We make no secret, Venerable Brethren, that the first sentiment we felt in our heart, prompted certainly by the goodness of God, was the inexpressible yearning of a loving desire for the salvation of all mankind, and in assuming the Pontificate our sincere wish was that of Our Lord Jesus Christ Himself, when about to die on the Cross: "Holy Father, keep them in Thy name, whom Thou hast given me" ( John xvii. 11).
