20 For transgression of the law, whether in small or great matters, is of equal moment;

IV Maccabees 5:20 In-Context

18 And indeed, were our law (as you suppose) not truly divine, and if we wrongly think it divine, we should have no right even in that case to destroy our sense of religion.
19 think not eating the unclean, then, a trifling offense.
20 For transgression of the law, whether in small or great matters, is of equal moment;
21 for in either case the law is equally slighted.
22 But thou deridest our philosophy, as though we lived irrationally in it.
