An Eritrean Oriental Orthodox Tewahedo Nun's Comments
Format: Kindle
For 28 years I served (with a lowercase "s" ) alongside my Eastern Orthodox husband/Archpriest, who reposed in 2018. Now as a Tewahedo Hermitess, with access to the world rather than strict enclosure inside the monastery, little father John Climacus' book serves as a helpful reference guide to me to determine how Eastern (communion) coenobitic monks during post-Chalcedonian Schizm tried to refine and perfect the more ancient Syriac strivings of stages of spiritual perfection started first by the "Sons and Daughters of the Covenant" transformed into a "narrow path to salvation" inside tonsured communities. While we do not use little father John's book as a key "focal point" in our Oriental Churches, it is important to preserve this copy - true to its original content - like all watershed moments in Orthodox Church History, and investigate if there are living parallels of little Father John's system used by Oriental monasteries, written by their respective Hegumens, within the same relevant time period. I am guessing there are probably so, because what Christ truly teaches and inspires, He never usually leaves to one person alone. "Where 2 or 3 are gathered together in My Name, there Am I in the midst of them" is the Peace of the Apostolic covenant of Christ, among the Churches founded by His 12 Apostles - a Peace and a symmetry that still can be found despite the heartbreaking misinformation, bias, and (in some spots of the world) bitter kernels of monastically - engendered hatred towards reunification of Eastern and Oriental communities into one, whole, functional and understood Church. He who has ears, let him hear (and examine)!

The Essential Work Other Than the Bible for Orthodox Christians
Format: Kindle
I just finished reading The Ladder for the fourth time. I read it every Great Lent before our Sunday of St. John Climacus. It is stern and austere being written for monks, but glorious in the lessons it provides for those of us not monastics. It is a roadmap to a Christian life, challenging and aspirational, inspiring and humbling. I learn something new with each reading, and my faith deepens. But been non-Christian readers can profit from this, as it is a great meditation on a life well loved, and an excellent depiction of the essence of a dedicated Christian life.

Great spiritual guide
It’s a fairly confusing book if you don’t know a lot about the Orthodox Church. But for anyone with enough patience to want to learn how to grow spiritually this is perfect.

Will lead you on the good path
Format: Paperback
I’ve barely made my way through the rungs of the ladder, but this book is definitely one of the greater books I’ve read, however I will say that people are right when they say this specific copy has a quite a few spelling errors, but I’m personally able to manage it well. I must warn you though, THIS IS NOT A LIGHT READ, if you’re looking for something simple to learn from, look elsewhere. This book isn’t an easy pill to swallow if you’re not open minded and at least somewhat familiar with the theology of the early church fathers, however if you are, I highly recommend you give this a read if you haven’t already. Once again, a fantastic read, but read at your own discretion.
