Faultless, unblamed - Berry's New Testament Synonyms

Faultless, unblamed

ἄμωμος, ἄμεμπτος, ἀνέγκλητος, ἀνεπίληπτος.

ἄμωμος is faultless, without blemish, free from imperfections. It refers especially to character. ἄμεμπτος is strictly unblamed, one with whom no fault is found. This of course refers particularly to the verdict of others upon one. ἀνέγκλητος designates one against whom there is no accusation, implying not acquittal of a charge, but that no charge has been made. ἀνεπίληπτος means irreprehensible, designating one who affords nothing upon which an adversary might seize, in order to make a charge against him.
