Jacques Maritain was one of the most formative figures of the interwar period, with enormous influence over what came after the Second World War through Pope Paul VI and the Second Vatican Council. Maximus the Confessor was one of the greatest defenders of the Roman Primacy and Catholic doctrine at the time of the Monothelite Crisis of the seventh century. Both were deeply concerned with the way in which the individual is perfected through the Mystical Body of Christ, and yet Maritain's view tends to lead to modern individualism, while Maximus' view fits in more clearly with the modern Catholic vision of the Social Kingship of Christ. Presented in Gardone, Italy in July of 2018.
