Immortale Dei §8

⁸ For the only-begotten Son of God established on earth a society which is called the Church, and to it He handed over the exalted and divine office which He had received from His Father, to be continued through the ages to come. "As the Father hath sent Me, I also send you."' "Behold I am with you all days, even to the consummation of the world."(6) Consequently, as Jesus Christ came into the world that men "might have life and have it more abundantly,"(7) so also has the Church for its aim and end the eternal salvation of souls, and hence it is so constituted as to open wide its arms to all mankind, unhampered by any limit of either time or place. "Preach ye the Gospel to every creature."(8)
