The period from Easter to the Day of the Holy Trinity is the most important from a liturgical point of view, because on these days the Church remembers such events of New Testament history that became fundamental in the work of our salvation: the Glorious Resurrection of Christ and the birth of the New Testament Church. The Sundays between these two holidays are dedicated to revealing the deepest dogmatic themes: victory over death, healing of human nature from sin, and the action of the Holy Spirit in the world. This book provides the Apostolic and Gospel readings read in church on Sundays between Easter and Trinity, in Church Slavonic and Russian with brief explanations, and also provides reflections on the theme of each Sunday Gospel reading.
