Ariel 2006, p. 191: „In the late 1960s and 1970s, both Jews and Christians in the United States were surprised to see the rise of a vigorous movement of Jewish Christians or Christian Jews. For many observers, such a combination seemed like an oxymoron, because they saw the two faiths as completely separate from each other. While Christianity started in the first century of the Common Era as a Jewish group, it quickly separated from Judaism and claimed to replace it; ever since the relationship between the two traditions has often been strained. But in the twentieth century, groups of young Jews claimed that they had overcome the historical differences between the two religions and amalgamated Jewish traditions and customs with the Christian faith. Attempting to overcome the historical difference between the two religious traditions, these Jewish converts to Christianity define themselves as Messianic Jews, thus pointing to the movements ideology of returning to the roots of the Christian faith.“
