91 Drawn from the treasures of Church teaching, the proposals of this sacred synod look to the assistance of every man of our time, whether he believes in God, or does not explicitly recognize Him. If adopted, they will promote among men a sharper insight into their full destiny, and thereby lead them to fashion the world more to man's surpassing dignity, to search for a brotherhood which is universal and more deeply rooted, and to meet the urgencies of our ages with a gallant and unified effort born of love. Undeniably this conciliar program is but a general one in several of its parts; and deliberately so, given the immense variety of situations and forms of human culture in the world. Indeed while it presents teaching already accepted in the Church, the program will have to be followed up and amplified since it sometimes deals with matters in a constant state of development. Still, we have relied on the word of God and the spirit of the Gospel. Hence we entertain the hope that many of our proposals will prove to be of substantial benefit to everyone, especially after they have been adapted to individual nations and mentalities by the faithful, under the guidance of their pastors.
