In April 2014, Tony Kan gave an address on Pesach (Passover). In his address, he gave a summary of the traditional Passover Seder, and discussed some major themes that arise from the material. In particular he focused on the themes of Jewish identity and Freedom from Slavery.
His discussion of Jewish Identity covered the complex issues which arise when this topic arises as it is not just a question of race, but faith and other issues.
Freedom from slavery is a marquee theme of Passover and he discusses the biblical basis for why this injustice should be fought by all believers. Kan also gives survey of Modern Slavery and gives evidence of its presence in modern New Zealand.
