17 All unrighteousness This passage may be explained variously. If you take it adversatively, the sense would not be unsuitable, “Though all unrighteousness is sin, yet every sin is not unto death.” And equally suitable is another meaning, “As sin is every unrighteousness, hence it follows that every sin is not unto death.” Some take all unrighteousness for complete unrighteousness, as though the Apostle had said, that the sin of which he spoke was the summit of unrighteousness. I, however, am more disposed to embrace the first or the second explanation; and as the result is nearly the same, I leave it to the judgment of readers to determine which of the two is the more appropriate.
