In case you missed it, Phil Johnson of Pyromaniacs has written a very helpful primer on antinomianism, including the various “strains of theoretical antinomianism.”

In totally non-technical terms, antinomianism is simply the view that Christians are not bound by any of the precepts of Moses’ law—moral, civil, ceremonial, or otherwise.

The Reformers saw three proper uses of the moral precepts of Moses’ law. Here’s a summary from Article VI of the Lutheran Formula of Concord (the "Epitome," or short form):

"The Law has been given to men for three reasons: 1) to maintain external discipline against unruly and disobedient men, 2) to lead men to a knowledge of their sin, 3) after they are reborn, and although the flesh still inheres in them, to give them on that account a definite rule according to which they should pattern and regulate their entire life."

In other words, the "third use of the law" makes the law’s moral standards the rule by which the faithful must order their conduct. In this sense, the moral strictures of the law remain binding on Christians, even though we are "not under the law" in the Pauline sense—i.e., not dependent on our own obedience for any part of our justification. (By the way, the entire Formula of Concord’s Article VI is a brilliant refutation of antinomianism, and well worth reading.)
