As several sources point out, antinomian is mostly an epithet directed at opponents, who on closer inspection are usually not claiming any across-the-board right not to obey laws. Some years ago in Reason I noted that certain writers in religious-conservative and neocon circles — the sort of circles where Colson’s name has much currency — were tending to adopt the word as a catch-all description of the modern world’s disrespect for established authority.

the proposition that it’s just fine to violate laws and court orders when one feels impelled by a higher cause — I believe some social conservatives like to label this point of view as antinomian

That isn’t what antinomian means (and I’ve never heard that belief labelled such).
antinomian: one who holds that under the gospel dispensation of grace the moral law is of no use or obligation because faith alone is necessary to salvation

For most social conservatives, or at least for most Christians, the law referred to in that definition would be the Mosaic, Old Testament law, not 21st century US law.

The belief that non-biblical laws should be disregarded when they conflict with what God requires doesn’t have a fancy name that I’m aware of, though it is certainly a biblical concept:
Acts 5:29 “But Peter and the apostles answered, ‘We must obey God rather than men.'”

It’s civil disobedience if it conforms roughly with the standards set forth in “Letter from Birmingham Jail”. Like openly acknowledging violating the law and submitting oneself to whatever punishment may be meted out, however unjust.

I don’t see those contours here.

Yes, they call that civil disobedience. It was quite popular back in the early 1960s. There was a lot of chatter about higher causes, and more than a few preachers involved. When civil disobedience is happening, it’s typically criticized. Years later, almost everyone pretends they were a supporter and never had a problem with the law breaking.

Note that I’m not commenting on this particular case, since I know nothing about it, just the rather inflexible suggestion that “laws and court orders” ought always to be obeyed. I find that a bit shallow and its use in an issue of this importance a cheap trick.

There’s also the term “Religious Right” in what can only be called ‘scare capitals.’ In English, capitalization in that context is only used of things that are sharply defined: Ford Motor Company and the United Auto Workers, but not auto makers or auto workers.

A group that encompasses Jews (Orthodox to Conservative), Protestants (Pentecostals to Episcopalians), the Eastern Orthodox (Russian and Greek), as well as Mormons (one wife or several), is far more like auto workers than it is the United Auto Workers.

The proper term is religious conservatives in small letters.
