by Timothy (Bishop Kallistos) Ware (2nd addtion). A clear, detailed introduction to the Orthodox Church containing the history, beliefs and worship of the Church. A valuable work, though unfortunately oriented towards the ecumenical movement. 358 pages, softcover.
Note: We recommend also buying the book THE ORTHODOX CHURCH and THE ORTHODOX WAY REVIEWED (search with: OCOW) by Hieromonk Patapios to help evaluate certain modernist and ecumenical positions in the Orthodox Church.
