I would suggest Orthodox Faith and Life in Christ
, and The Orthodox Church and Ecumenism
, by St. Justin Popovich. The first is a collection of essays that touches upon everything from epistemology to the lives of the saints, and the second one is about Orthodox ecclesiology, ecumenism, humanism, etc. Both are available through St. Nektarios Press
If anyone slaps you on the right cheek, challenge them to a fight. If anyone wants to sue you and take your shirt, air their dirty laundry. If anyone forces you to go a mile, berate him continually. Give to those deemed worthy (if they pass a drug test), and turn not away from billionaires in need of tax breaks. This is [not] the Gospel.
