Patristic Ethics

I am very interested in the Ethical formulations of early Church leaders during the Patristic period of Church history. I think the thing that I find most interesting about them is the fact that they set the foundations for what the church would be built on during a time of great persecution. Many of these men were killed for what they believed, yet the worked with their lives on the line to formulate and characterize what it meant to live as a Christian in their time and how to live an upstanding and moral life. We are indebted to the efforts of these early church leaders.
