ἀναπολογήτους: "without excuse"

Says εἰς τὸ εἶναι αὐτοὺς ἀναπολογήτους means "so that they are without excuse." The adjective ἀναπολόγητος (anapologētos) is the negative of ἀπολογία, a legal defense. It recurs at 2:1, where it is applied to the one who judges others.

Says Abbott-Smith gives the sense "without excuse, inexcusable." The word belongs to the language of the courtroom.

Implies εἰς τό + infinitive here expresses result: "so that they are". It may also express purpose. Either way the verdict is forensic. No defense of ignorance is left, because knowledge of God was given and then suppressed (1:18–21). This prepares for 3:19, "so that every mouth may be stopped."

Uncertain Whether εἰς τό marks purpose (God's intent) or result. Paul uses the construction both ways. The team reads result, with God's just intent not excluded.
