From what has been said, it is evident that liturgical life in Russia is divided into three periods, characterized by the dominance of various statutes.

The first period, until the end of the fourteenth century, is connected with the introduction by the Monk Theodosius into the liturgical practice of the Russian Church of the rule of the Studite monastery.

The second period is associated with the appearance of the Jerusalem rule, translated into Slavonic by Athanasius, the abbot of the Vysotsky monastery in Serpukhov. At the end of the fourteenth and the beginning of the fifteenth centuries, the same statute was universally recognized.

From the beginning of the sixteenth century, the third period begins: the development of local statutes under the rule of the Jerusalem rule.

The liturgical rites of our Church are not fully embraced by the above-mentioned statutes. Throughout the history of the Russian Church, they represent an almost continuous change of some features by others, the simplest editions of the rites by more complex ones.4

But with constant change - the addition and disappearance of liturgical features - the addition prevails over the disappearance. The composition of the service is constantly increasing. However, not all aspects of the divine services changed equally.5 The change in the rites affected the content and composition of the liturgical books. We will dwell on the study of some of these books.

2. Trebnik

A Trebnik is a liturgical book that sets forth the rites of the Sacraments and other sacred actions performed by the Church on special occasions and are not primarily part of the temple (public) worship of the daily, weekly and annual cycle.

The book received its name from the word "treba", which in the Old Russian language had a sacred meaning and meant "sacrifice", "sacrifice", "prayer", "performance of a sacred rite".6 At present, the word "treba" refers to prayers and sacred actions performed at the request (according to needs) of one or more Christians in special circumstances of their lives. This refers to all the Sacraments (except for the Eucharist and consecration), molebens, panikhidas, funerals, consecration of houses, and so on.

History of origin

Trebnik

In their origin, the rites of the Sacraments and other sacraments set forth in the Trebnik date back to the time of the apostolic life of the Church. The original Trebniks have not come down to us.

The earliest known sources are the Euchologion of Sarapion, Bishop of Thmuit (Egypt, 4th century), as well as the collection of prayers and services contained in the 8th book of the Apostolic Constitutions.

As the external side of the divine service developed, the number of prayers increased until the eleventh century inclusive.
