St. John Damascene

St. John was born around the year 676 in Damascus, and spent all of his life under Muslim rule. 

He is famous first of all for his writings against the iconoclasts, who opposed the veneration of images. Paradoxically, it was the Eastern Christian emperor Leo who forbade the practice, and it was because John lived in Muslim territory that his enemies could not silence him. Secondly, he is famous for his treatise, Exposition of the Orthodox Faith, a summary of the Greek Fathers (of which he became the last). It is said that this book is to Eastern schools what the Summa of Aquinas became to the West. Thirdly, he is known as a poet, one of the two greatest of the Eastern Church, the other being Romanus the Melodist. His devotion to the Blessed Mother and his sermons on her feasts are well known.

St John died in 749. His Feast Day is December 4th.
