Query: Who leads the movement that pursues secular Jews in order to give them stronger Jewish identity?
Context: There is also a trend of Orthodox movements pursuing secular Jews in order to give them a stronger Jewish identity so there is less chance of intermarriage. As a result of the efforts by these and other Jewish groups over the past 25 years, there has been a trend (known as the Baal Teshuva movement) for secular Jews to become more religiously observant, though the demographic implications of the trend are unknown.
