This book will help you not only navigate a large number of Orthodox holidays and fasts, but also find out what you can eat and what products, if possible, not to use on fast days. And what dishes to cook for Christmas, Trinity, Easter, summer Spas and winter Christmases. The history of Orthodox holidays dates back to the Old Testament. Holidays that originate in the New Testament time also adjoin the Orthodox. Each of the Orthodox holidays is dedicated to the memory of the most important events in the life of Jesus Christ and the Mother of God, as well as the memory of holy saints. Recognizing the holidays as useful from the point of view of piety, the Church always informed their celebration of a solemn nature, while the sacrament of the Eucharist or the communion of the Holy Mysteries was considered a prerequisite. According to this, the whole life of Christians was arranged on holidays: they freed themselves from worldly activities and labors, did not arrange noisy amusements, feasts, but consecrated them with charity in favor of the Church and the poor.
