I respect the point you are trying to make, in regards to your original question. Nineteen pages later, the topic has gone awry a few times, but the off-topic points do point back to the same basic truth. These questions are related in a reasonable way, and I hope you’re seeing the reason behind that.
I have considered before that a gay couple should have the same legal recourse as a traditional couple, myself. In regard to the claims on mutual property, they certainly should, in the case of an end to their relationship. Now, I’m not a lawyer, but I believe that recourse to the law already exists, basically, without defining their relationship as a marriage-like union. What is unacceptable to me, and all Catholics, and all other people with what clarity of mind they may have, about acknowledging a gay couple as a legitimate union (entitled “marriage” or not) is the effect that it has on society in general. The effects are manifold, and they are poisonous. They are adopting children now and raising them into a culture that is abominable, teaching these innocents to live a lie and to spread lies, twisting the definition of not only marriage, but love. It is a mockery to the natural order of life, and an outright disobedience to God’s commandments. Now, the Church, an institution of love, is being twisted in the views of society to be judgemental and hateful, when we are really just trying to live the life we are commanded to live.
We are not trying to be “superior.” We are not to judge. Yet, the Church was established to be the pillar and bullwark of the truth. We are obligated to lead all people (to the ends of the earth) to Jesus. It is our work “to bear good fruit.” We must do what we can to stop the spread of homosexuality. Historically, there have been homosexuals for thousands of years, and there will be until the end, no doubt. We are to love them and help them as much as any other brother and sister, but are not to support them in acts of sin. Support on a civil level would do an immeasurable amount of damage to our society. The general support they have received so far has only helped to increase homosexuality. Those tempted to follow such lusts may have otherwise rejected such a way of life instead of embracing it, simply because it is more acceptable in our society. People are naturally sexually curious. We are all tempted. Those not firmly taught in the teachings of the Church, faithful and strong enough to resist temptation, have nothing but the attitude of their peers and their own feelings to base their decisions on. Why would we not do everything in our power to stop as many souls as possible from going astray? We can’t just preach to the choir, keeping our way of life locked away inside our churches and our homes. We are commanded to shine the light of truth to all. So, that is what we do.
