This work was written by a monk of St. Tikhon's Orthodox Monastery in the northeastern region of Pennsylvania. It is a concise, newly revised exposition of the traditions, teachings and practices of the Orthodox Church. It is also an extensive work, and perhaps, one of the fullest English language catechisms for those entering the Orthodox Faith (Or those Orthodox and non-Orthodox who want to broaden their knowledge of what the Orthodox Church teaches).
This book is just amazing and I've read many. It teaches you everything a convert needs to know. Its almost like an instruction manual of the who, what, when, where, why and how. Its just perfect.
