Another fantastic commentary from the Daily Gospel Apostolate:
Vatican Council II, Message to Youth
It is to you, young men and women of the world, that the Council wishes to address its final message. For it is you who are to receive the torch from the hands of your elders and to live in the world at the period of the most gigantic transformations ever realized in its history. It is you who receiving the best of the example of the teaching of your parents and your teachers, are to form the society of tomorrow. You will either save yourselves or you will perish with it.
For four years the Church has been working to rejuvenate her image in order to respond the better to the design of her Founder, the great Living One, the Christ who is eternally young. At the term of this imposing re-examination of life, she now turns to you. It is for you, youth, especially for you that the Church now comes through her Council to enkindle your light, the light which illuminates the future, your future.
The Church is anxious that this society that you are going to build up should respect the dignity, the liberty, and the rights of individuals. These individuals are you. The Church is particularly anxious that this society should allow free expansion to her treasure ever ancient and ever new, namely faith, and that your souls may be able to bask freely in its helpful light. She has confidence that you will find such strength and such joy that you will not be tempted, as were some of your elders, to yield to the seductions of egoistic or hedonistic philosophies or to those of despair and annihilation, and that in the face of atheism, a phenomenon of lassitude and old age, you will know how to affirm your faith in life and what gives meaning to it, that is to say, the certitude of the existence of a just and good God.
