The same bureaucratic twits who pretend to love Gaudium et Spes also tend to ignore the issues in every neighborhood that can be addressed much more easily neighbor to neighbor by normal people and normal pastors and parishes! If at the lowest level in the Church (the basic family unit and the parish) these teachings were emphasised and prioritized, society would not be broken, the Church would not be so weak, and the Church would and its members would be in a better situation to address all the other issues in G et S!
G et S:
Paras 27 and 51 condemn abortion and demand we oppose it.
Para 47-51 are all about the duty to foster traditional ideals of marriage, procreation and family.
To finish my thought:
The so-called "G et S - lovers" focused on obvious political concerns (expandng state-run welfare & medical services, nuclear arms) and ignored pastoring the flock regarding elemental faith and morals, such as the proper understanding of the most basic of basics for EVERY person - marriage, procreation & family (EVERYONE is a result of procreation and part of a family, even if they don't get married and eventually procreate themselves).
If we get marriage, procreation and family wrong, then the members of the family don't properly understand their Creator, His love, and their response to that love and their purpose in life, society suffers tremendously, the Church loses influence in society, and no one really understands or cares about the Church's view about all the other issues.
Rant over.
