The EO definition of Canon is those books which are read in the context of the Liturgy. There are also different levels within the Canon, the Gospels being at the top. Revelations is included with 1 & 2 Clement, the Shepherd of Hermas and a few other early texts that are considered worthy of reading, but are not read in the Liturgy itself. It used to be extremely uncommon to have a single volume containing all the books of the Bible in the Church. The Gospels were one volume which is kept on the altar except when the priest is reading the day's gospel reading, the Psalter is another volume as is the Praxapostolon containing Acts and the Epistles, and other volumes contain the Old Testament and the various hymns for the feast days celebrated throughout the year.
