Antinomianism - True and False by D M Panton and published by Classics.
Antinomianism – a term invented by Martin Luther – means ‘against law,’ that is , an antagonism to all law for the child of God. In its extreme form it is a revolt against all law for the saved soul so drastic as to receive the challenge of Paul – “Shall we continue in sin, that grace may abound?” (Romans 6: 1).
If the grace of the Gospel covers a [regenerate] believer’s present [wilful] sin, sin known and continued, then the more sin, the more covering grace; to continue in sin, therefore, is to multiply grace. Here it is in its full nakedness. Put thus tersely and tensely, the whole Church of God responds – “God forbid!” But the diluted Antinomianism which we are confusing to-day is a subtle form of the same error; namely, that while we must not sin that grace may abound, if we do sin, grace will abound, so covering it, whether it is confessed and abandoned or not.
