The teaching of the Church about how to love our neighbor comes to us through two millennia of apostles, prophets, evangelists, pastors, teachers, saints, philosophers, thinkers, and reformers pondering the implications of Jesus' teaching and, what is more, living it out. Catholic Social Teaching can be pictured as a throne sitting on four pillars. Just as a throne would tip over if the legs were all of varying lengths, these pillars are equally important and equally emphasized by the Tradition. Or, if you prefer, they are like four notes forming a single chord.
