'Legally' in the Bible

So then, if Demetrius and the craftsmen who are with him have a complaint against anyone, the courts are in session and proconsuls are available; let them bring charges against one another there.

He has qualified us [making us sufficient] as ministers of a new covenant [of salvation through Christ], not of the letter [of a written code] but of the Spirit; for the letter [of the Law] kills [by revealing sin and demanding obedience], but the Spirit gives life.
