Christ and the Law in Matthew
Martin argues that Jesus' relationship to the law is not described in terms of keeping (terein), doing (poiein), establishing (histemi), making firm (bebaioun), interpreting (hermeneuein), adding (prostithemi), completing, or making perfect (telein or teleioun), but of fulfilling (pleroun). Jesus' eschatological mission is not in any way to take away from the law, or add a foreign mixture to the law, but to fill the law full, to bring all of it into eschatological fullness. This he does in the events of his coming, his earthly life, death, resurrection, and return, but he also does it with his teaching.
