Apostolos: The Liturgical Book of the Eastern Orthodox Church
In the rich tradition of Eastern Orthodox liturgy, the Apostolos serves as a vital liturgical volume. This book contains a curated collection of sacred texts traditionally attributed to the twelve apostles, the primary disciples of Jesus Christ. During a church service, a specific passage is selected from the Apostolos to be read aloud to the congregation.
The Apostolos is strategically positioned within the order of service, serving as the reading that immediately precedes the Gospel Reading, thereby preparing the faithful for the words of Christ.

Contents and Liturgical Use
The primary purpose of the Apostolos is to provide the scriptural foundation for the day's service through the writings of the early church leaders. The book consists of the Acts of the Apostles (which chronicles the early history of the Christian church) and various epistles (formal letters written by apostles to early Christian communities).
Because the Apostolos is central to the worship experience, it has been a subject of significant interest for printers and scribes throughout history.
Historical Examples of Printing
Notable historical editions of the Apostolos highlight the spread of printing in Eastern Europe. For instance, Ivan Fyodorov, a pioneer of printing, published an edition of the Apostolos in Moscow in 1564.
Further evidence of this printing tradition can be seen in the 1574 edition of Ivan Fyodorov's Apostolos published in Lviv.
