Jesus calls individuals, not groups; if you want to call them persons, that’s fine, but we’re still talking about only one person at a time. It is the individual believer who accepts the gift of faith, and also the individual believer who is then responsible for his own acts and for following the Lord in his own way. It is the individual who is baptized into the Church, the individual who tells the priest that he has accepted the Faith and rejected Satan.
He then becomes part of the Body of Christ, and also part of other units (family, monastery, etc.), but it is always his unique act of faith that has brought him there. Obviously, we are all part of some institution or entity of one kind or another, and there are good ones and bad ones.
But Jesus would never have called the lame, the halt and the blind if it were all up to a person’s having developed in a healthy form. Even the most rejected, neglected and isolated individual can accept the Word of the Lord and become a Christian.
I’m not saying there aren’t better or worse situations, those that encourage or don’t encourage an individual to live a good life. But my point is that to base the argument against “gay marriage” on the statement that it’s not a healthy environment for children simply isn’t enough. If it’s all based on relative experience, you can certainly find enough people who had miserable two-parent homes and others who probably claim to have grown up quite successfully in a home where the parents may have been gay (although you’re certainly going to have a lot fewer of those).
The only argument against “gay marriage” is that it is simply not possible for human beings to redefine physical reality and declare that the law embedded in nature (both spiritual and biological) doesn’t exist because they don’t like it. The state cannot possibly go out and declare that two men can be “married” simply because the basis for the concept of marriage is actually a biological one and all the laws in the world won’t change that.
But, as I said, when some people are now announcing that a child’s biological sex is something that the child should “choose,” we see that this is absolutely a Luciferian rebellion against the Law of God which is inscribed in nature itself.
So it goes way beyond social structures.
I was (maybe confusingly) trying to address the question that Sivad originally brought up, about whether God's laws are for individuals only, or for "society in general," or for the State.
It's a good question. And I was trying to say that the societies which are instituted by Divine and Natural Law (the family and the Church) also play their part in His saving plan. There's a sense in which we are all saved as individuals; in another sense, none of us are saved as individuals. We are saved by being incorporated into Christ. Extra Ecclesia Nulla Salus. We say "Our" Father.
And there are moral laws applicable to the family as such, and in fact every level of human society. Look at all the constant Biblical concern for intermediary institutions, the comings and goings of tribes, the identification of kinship, the mustering of armies, the selecting and deposing of royal courts, the teaching and sending of authorized apostles, the appointment of deacons, etc.
One by one we my have unique callings and unique responsibilities, but there are also laws that pertain to societies. The "nation," also, is called to repent. "Israel" (used as a collective term) is summoned to heed God's statutes. The "Church" cares for the poor in Jerusalem.
Anyway, the concept of Subsidiarity helps here. Keep things as small and as local as you can. The more things fall out of the hands of the small groups, the intermediary societies, the more they are picked up by Leviathan. If we are totally absorbed into a Reich or Obamunism or a Collective from Hell, it'll be because we let them pick up the tasks we dropped.
