St Gregory of Narek has been recognized as the 36th Doctor of the Church. I think this is perhaps the most significant event within the Catholic Church since Vatican II; not surprisingly, almost completely overlooked in the world’s media. His feast day will be, I hear, February 27th.
His Book of Prayer, composed around the turn of the first millennium and also known as St. Grigor Narekatsi’s Book of Lamentations, is online in an English translation by Thomas Samuelian.
In her teaching office, the Church says, ‘The writings of these 36 saints are both important and reliable.’ Of course, in no way comparable to or in conflict with the canon of Scripture; however, useful in the ongoing life of the Church.
