The "no-holiness-now" advocates, be they Puritanical or antinomian, are united in the belief that holiness on earth is not for today. (Antinomian—the view that Christians are released by grace from the obligation of observing the moral law)
Holiness defines God's character, first and foremost. It is His complete "otherness" that distinguishes Him from us. He is "separate" from all creation. Yet both Testaments command God's people to be holy (Lev . 20:26, 1 Pet. 1:16). This three-time holy God makes holiness an imperative—"Be ye holy."
