Jean-Yves Leloup, an Orthodox theologian, is well known in Europe, North and South America as a popular author on spirituality and psychology. He is the founder of the Institute of Other Civilization Studies and the International College of Therapists. He has written more than fifty books and has also translated and commented the gospels of Thomas, Miriam of Magdala, Philip and John.
The Gospel of Thomas as assembled from a buried jar of codices and manuscripts discovered in Upper Egypt in 1945 is a collection of Christ's teachings in 114 logia (or sayings). It is not about the life of Christ necessarily, but provides a dimension not emphasized in the Bible--Gnosticism. A comment by Jean-Yves Leloup after each logion, the founder of the Institute of Other Civilization Studies, helps the reader understand in more depth the meaning of each saying.
This is one of the first books I was introduced to when discovering the Gnostic text. It's a great read and does some really great gospel text comparisons to the traditional New Testament Bible. I reference this book in my book, The Christ-Like Spirit: Relationships as a Spiritual Practice.
