The principles of Catholic Social Teaching are often referred to as the church’s “best kept secret”. While these principles are at the heart of Christian living, sadly many Catholics are either unaware of the them, or simply ignore them, often due to the challenge and personal cost involved in putting the principles into concrete practice. The biblical understanding of “justice,” right relationship with God, others, the human family and all of creation, undergirds Catholic Social Teaching. God calls us to honor, respect and protect the dignity and worth of every human person, along with all that God created. Knowing the principles of Catholic Social Teaching is essential in faithful Christian living, guiding us in building up the reign of God on earth, based on justice and right relationship the human family and with all of God’s creation.
