One area in which this principle has demonstrated itself time and again is the laws governing family purity. The requirement instituted by the Chief Rabbinate of South Africa in the mid ’70s that all couples marrying under its auspices (i.e. almost all South African Jews) would receive private one-on-one instruction in the laws of family purity is generally believed to be one of the major impetuses of the powerful teshuvah movement that swept the community in the 1970s and ’80s.
