Catholic church teaching on its relationship to other religions since Vatican II

My intention is to provide a speedy tour through the past forty years focussing on theological and rhetorical shifts in major Church documents and papal pronouncements on Catholic approaches to religious pluralism. This tour will focus on three questions: (1) Has there been a shift in the Church's teaching on Non-Christian religions as such? (2) How does the Church understand religious dialogue in context of its evangelising mission? (3) What are some of the outstanding theological and rhetorical issues arising from these documents and pronouncements
