Catholic social teaching is an influential guide to living one’s faith in tangible, real-world ways. It teaches us how to care for others and the earth. These teachings are not something to be confined to the church. They can form the way that we engage poverty, seek justice, and provide care to the earth on an everyday level. Thom O’Leary reminds us frequently that faith is to result in action, particularly when people are in need and when creation is under duress.
