Another term is "Gospel Reductionism".
Therefore, there is now no condemnation for those who are in Christ Jesus. Romans 8:1
For I resolved to know nothing while I was with you except Jesus Christ and him crucified. 1 Cor 2:2
Whoever believes and is baptized will be saved, but whoever does not believe will be condemned. Mark 16:16
There are very few people who openly claim the name Antinomian. But I've met many who were effectively Antinomian in their faith walk. In different cases, I've seen discussions of sin, social responsibility, and even good works "shut down" by repeating one of the three verses above.
In other words, "there is no condemnation" is read as "no need to examine my conscience." "Knowing nothing but Christ" is read as "stop talking about knowing the needs of others." "Whoever is baptized" is read as "I'm baptized, stop talking about morality."
