Over the next several weeks, I will reflect on Joseph Cardinal Cardijn’s philosophy/theology of praxis in relation to the Sermon on the Mount. For Cardijn, his theology was grounded in the Sermon on the Mount. From that understanding, he saw avenues to put theology into practice. For Cardijn, that was in YCW and YCS. For Cardijn, his lifelong dedication to social activism and working toward improving the working class was paramount.
