The members of the Church are impelled to carry on such missionary activity by reason of the love with which they love God and by which they desire to share with all men the spiritual goods of both its life and the life to come.
Finally, by means of this missionary activity, God is fully glorified, provided that men fully and consciously accept His work of salvation, which He has accomplished in Christ.-Ad Gentes 7, Vatican Council II.
