Dear ones in Christ,
There are six books which comprise, by far, the very best of my spiritual reading over this past year, and which have not yet been mentioned in this thread:
1) Monastic Wisdom: The Letters of Elder Joseph the Hesychast. Florence:St Anthony's Greek Orthodox Monastery, 1998. [Reading this book, one understands why the priest entreats God during the Divine Liturgy that he will grant us sobriety of soul...]
2) Archimandrite Ioanichie (Balan). Shepherd of Souls: The Life and Teachings of Elder Cleopa, Master of Inner Prayer (1912-1998). Platina: St Herman's Press, 2000. [I have become acustomed to give a copy of this book to our catechumens while I prepare then for baptism because I know of no better way for them to enter in contact with something far beyond our poor Church life --the everyday implications of the very life and phonima of the Holy Church-- short of moving them to Sihastria or Ostrog!]
3) Elder Cleopa (Ilie). The Truth of Our Faith: Discourses from Holy Scripture on the Tenets of Christian Orthodoxy. Thessalonica/London:Uncut Mountain Press, 2000. [Suffice it to say that which the people said of Our Lord when the fullness of time had come, and the Word dwelt among us: "He speaks as one with authority".]
4) Protopresbyter Dumitru Staniloae. Orthodox Spirituality: A Practical Guide for the Faithful and a Definitive Manual for the Scholar. South Canaan:St Tikhon's Seminary Press, 2002. [This is like a mirror, and a powerful examination light, to help us comb the depths of our souls, our affections, and our motivations.]
5) Protopresbyter Radomir Nikchevich and Vesna Nikchevich. The Mystery of the Wonderworker of Ostrog. Cetinje:Svetigora, [date?]. [Both the story of the transformation of the young man who comes to the Ostrog Monastery, to the relics of the saint, genuinely seeking, as well as the introduction to the life and miracles of St Basil --glory of Orthodox Montenegro-- cause a radical shift in the outlook of as many of us as may have a flawed expectation (and experience!) of the life in Christ, and cause in one the burning desire to live supernaturally, by God's grace.]
6) Demetrios Aslanadis and Monk Damascene Grigoriatis. Apostle to Zaire: The Life and Legacy of Blessed Father Cosmas of Grigoriou. Thessalonica/London:Uncut Mountain Press, 2001. [Again, the life of the Church, the mind of the Church, shine through every page, and teach us converts to never settle for less than what has been handed down to us from the days of the Apostles, no matter how preacarious our situation; for to do otherwise, reveals a profound lack of faith in the power of God, who could make the desert flourish, and cities become deserts.]
