I have discovered a website that offers an intellectual discipline for those interested in early church writings.  They have put together a plan of readings, which they describe as follows:

By reading seven pages a day for seven years, you can study a vast library of theology, history, liturgy, apologetics, biblical commentary, and devotion written in the first seven centuries of the Christian church. We provide a schedule of readings, the texts in English translation, and—most important—a community to discuss what you’re learning. Laypeople, clergy, seminarians, students, and Christians of all denominations will benefit from joining our community to read the church fathers.

They are in year 3 of this project, and have covered works written by such luminaries as Origen, Hippolytus, Tertullian, Clement of Alexandria, Irenaeus, and Justin Martyr.
