Reverend Ephraim the Syrian (IV century) was born in the ancient Mesopotamian city of Nisivin and, having accepted monasticism, became famous for the height of his spiritual life. During his lifetime, the works of Saint Ephraim were translated into other languages and even read in churches after the Holy Scriptures. Reading the prayer works of St. Ephraim is essential and saving for the Orthodox soul. In the works of St. Ephraim the Syrian translated to this day, Russian pious people have found and are finding one of the most abundant sources of spiritual edification. The sincere desire to make this source accessible to Russian people, if possible in all its parts, prompts us to now offer readers a translation of two interpretative works of St. Ephraim the Syrian that have not yet appeared in Russian, namely: his interpretation of the epistles of the Holy Apostle Paul and the Four Gospels .
