The Gospel Book is divided into three parts. The first part holds the Gospels for the period of the Resurrection Season (St. John), the Pentecost Season (St. Matthew), after the Sunday following the Exaltation of the Holy Cross (St. Luke) and the Triodion Season (St. Mark). St. Mark is also read during the week after the eleventh week of St. Matthew and the thirteenth of St. Luke. The second part carries the Gospels for the Feasts of the Menaion. The third part holds Gospels for different occasions.

Basic Rules:

• For all practical purpose, we should read the Gospel of the first part of the book. The addition of the Menaion Gospel from the second part is permitted but not practiced.
• There are special Gospels to be read on certain Saturdays and Sundays of the year from the second part. This second part also provides Gospels for the period of January 6 to 14 and September 10 to 14 in the case the first is consummated due to the occurrence time of the Feast of the Resurrection.
