 Most commonly, Israel is seen as distinct from the church; Messianic Jews, being a part of both Israel and the church, are seen as the necessary link between the 'gentile' People of God and the commonwealth of God's people of Israel.The two-house view, and the "one law/grafted-in" view are held by many identifying as Messianic, although some Messianic groups do not espouse these theologies.According to certain branches of Messianic Judaism, Jews are individuals who have one or more Jewish parents, or who have undergone halakhic conversion to Judaism.
