Antinomianism is a later term meaning "against the law". It doesn't mean some act that violates the law, but describes the idea that the entirety of the old testament law is abolished. Hence an individual who is against the law. If the law is abolished there is no sin, so a person can behave themself any way they want to and still be justified. Is there anyone here who holds to that belief or do you know anyone who does?
Actually antinomianism does not just include the O.T. law when it advocates that we are not now governed in any way by the law. Some definitions online say that. But that is not what the controversy is all about.
Antinomianism teaches that since salvation is by grace alone and not works, and it is, there is no reason to obey any moral law - written or not. We should even go on sinning that grace may increase. People in the scriptures wrongly accused Paul of teaching that because of his strong stance on salvation by grace.
People here in the forum quite often accuse those who preach against our success at being obedient to God having anything to do with salvation in the most basic sense (Heaven vs. Hell as it were) - of teaching antinominism just as they did Paul.
It's a straw man of course. No one here teaches that we are to sin that grace may increase or even, as some say grace only proponents teach, that there are absolutely no consequences to sinning now that we are saved. In fact, I don't believe I have ever heard anyone teaching that - here or anywhere else.
To those who quickly charge the grace folks with "antinomianism" - the only "consequence" they can think of for sinning is losing your salvation and spending eternity in the fires of Hell.
Like I said - it's a straw man used by those who would add works to the work of Christ in order to either get saved in the first place or to stay saved and not lose your salvation.
There are few if any antinomians in this forum. There are a great many of those who wrongly accuse people of being so, simply because they take a correct stand on the doctrine of eternal security for those who have been born again and actually saved.
After this post, one or two will likely pop up here on this thread. I would actually expect nothing less base on my experience with the great many here who wrongly teach various forms of works salvation.
I see that you of the Orthodox persuasion. While I can't know your exact view on the subject of salvation - I do know that Orthodox seldom speak of our being saved at this time. They generally teach that we are "being saved" by cooperating with God (i.e. - obedience to Him, various religious observances, rites and the moral law He has given us).
When a person points out that hoping to be saved in the end by being conformed to Christ's image through our yielding to God is not the way to salvation in the most basic sense (Heaven vs. Hell) - that person is quite often accused by the Orthodox Christian of teaching antinomianism.
I certainly hope that that isn't where you intended to go with this thread all along.
