I was under the impression you had reached the point of simple argumentation, which is why I was withdrawing. I may still pull out if I really don’t think we’re going to get anywhere, but now that you’ve corrected me about your approach, I’ll stick with it

. It has been a pleasant discussion, probably the first pleasant discussion I’ve ever had with someone about this. Thanks for the clarification about your approach!
While I’ve got a great understanding of the covenant relationship thanks to folks like Scott Hahn and my Eucharistic knowledge borders on the impeccable, my study of “the Law” in Old Testament/Covenant times is comparatively quite limited, especially the study of the applicability to those outside the nation of Israel. Thus, while I understand that the New Covenant in Jesus Christ extends to the whole human race regardless of Jewish heritage, everything I had studied as a Protestant had indicated that the Law was given to the Jewish nation, precisely because they were his chosen people.
This is the more comfortable approach in today’s society, but not the more traditional approach. It’s not even the traditional Protestant approach; Luther was all for executing prostitutes (after one gave him syphilis

), Catholics, Anabaptists, witches and lots of others. And Calvin and the others were much the same. The validity of Old Testament based (and New Testament tempered) civil law was accepted back then, but it’s changed a lot now, and most Catholics don’t hold to this anymore either.
But there are Early Church Fathers like Tertullian saying Gnostics ought to be compelled to hold to Christianity, and Polycarp saying to the Roman authorities, “away with the atheists,” and Augustine calling freedom of religion “freedom of perdition.”
There were Early Church Fathers who believed in freedom of religion too, but at least secular historians (I haven’t read that many religious historians yet) agree that they united in opposing it in the 4th and 5th centuries because this was the logical conclusion of their reasoning during the first few centuries. They certainly felt in basically the way I’ve described throughout the Medieval Ages and most of the modern era, before the 20th century. Now, things have changed a lot in the Catholic Church, but not in infallible teaching, and the social justice rules could revert back if perspectives changed.
You need to understand I’m advocating a more traditional Catholic position, though, an older one than the present normal point of view. I saw a poll once on Catholic Answers as to how many people thought atheism should be banned, and it was something like 8% of the four or five hundred voters. This is also a pretty conservative site. So I’m definitely the minority opinion today. Just to clarify that. And I don’t think you’ll find many Church leaders of today espousing the view that the Old Testament is still applicable in today’s society either. I think you’d be hard pressed to find any, though on the other hand I’m pretty pessimistic simply because I’m accustomed to always being the most disagreeable (opinion-wise) guy in any given group. Because I’m anachronistic. However, if you looked at the writings prior to the modern era, you’d be extremely hard pressed to find any that
disagree with what I’m saying.
I just want to clarify that I’m not expressing “the Catholic” position. I’m expressing what I believe to have been the normal Catholic position, a position I still believe in. So if you end up not believing me, don’t worry about it

. I don’t speak for the Catholic Church when I express my beliefs on this, and many of them would disagree with me about their history too. Though I know John Paul II didn’t, which is why he led a big act of contrition with the bishops for the “crimes” of the past popes in suppressing heretics. If I lived a century ago, I would feel comfortable about saying I’m expressing the normal Catholic position, in essentials.

I don’t think truth changes, and I don’t think they had it wrong before. I think we’ve been washed over in a tide of liberalism, and while the Church’s faith and morals are and always shall be intact, some of its social justice teaching, which is not protected by the charism of infallibility, is . . . well, I don’t agree with parts of it as it stands today.
What you seem to be implying is that the Catholic position is that God gave his Law and his mode of justice to all peoples, even before the advent of Christ.
Here’s a distinction I think we need to draw. I believe that God gave His Law to Israel and more than anyone else, they were called to obey it. They were, and are, the chosen people. However, the Law’s value holds whether applied among the Jews or the Gentiles because it is a universally just Law, a “perfect” Law. God revealed His truth to the Jews and the light shone out from Israel to the Gentiles, who saw it and in many places adopted parts of the Old Covenant into their own laws, for they were impressed by the justice of a number of the teachings. This can be seen in a number of nations that surrounded Israel in the past.
The Law includes commands in it to physicians to wash their hands in running water before trying to cure the injured, to quarantine sick people rather than letting them walk around the camp infecting everyone, and other practical commands that hold true in their value whether applied by Jews or Gentiles. Circumcision also has health value; if the Gentiles applied it, they would have benefited from this. The Law is simply perfectly valuable, good and true, as the Book of Romans says, and it doesn’t lose these characteristics if applied among the Gentiles simply because they aren’t Jews.
However, the Law was for the Jews especially, for they were and are God’s chosen people. If the Gentiles had come to understand the justice of the Law, they would have fallen under its obligations too, and in some places they were and they did, because they mimicked Hebrew Law in their own laws. Anyone who knows what is right is obliged to live like he does. These lands benefitted from obeying just principles their neighbors lacked. To the extent that people didn’t know God’s will, they were protected from part of their sin by “invincible ignorance.”
