I really liked this book, although it took much longer to read than I thought. I was hoping to finish by Easter! However, it was written by St. Nicholas Cabasilas in the 14th century and the original language was Greek. The book covers Orthodox theology regarding Baptism, Chrismation (what the Western Church calls Confirmation), and Eucharist (Holy Communion).
I bought this book in 1999, but it was only now that the Holy Spirit pushed my to pick it up and read it. I'm still not sure that I fully understood all of it and will have to meditate and pray on it for some time to come.
Then again, much of what I learned in the book about these mysteries fits in with what I learned at the Denver Catechetical School...
1) Until a person is washed in the waters of Baptism, they are an enemy of God. Okay, according to Cabasilas, the un-baptised are not enemies of God but are unknown to God. Our parents participate with God in the creation of a new life, but until the soul is Baptized, they are not known by God.
2) Confirmation (Chrismation) completes the instruction in the life of the Church.
3) Eucharist is the most important of these three mysteries or sacraments. By partaking of this meal, where we eat the Body of Christ and drink the Blood of Christ, we become the Body of Christ. At least in the case of the soul then, we truly are what we eat.
The final two "books" or chapters deal with what is required of the Christian to nurture the grace we receive from these mysteries or sacraments and how we train our will toward virtue and goodness in order to fully participate in the joy God wishes for us, with Him, in His kingdom. These are the chapters that I must re-read at some point in the future and pray on for now in order that I may gain a complete understanding of Nicholas Cabasilas.
