Today the Holy Church celebrates the feast of the Holy Apostle and Evangelist Mark. As with any of the four Evangelists – writers of the Holy Gospels, this is a significant day in the life of the Holy Church. Below we include the life of St. Mark for the edification of our readers. We wish all celebrating their name's days on this day many years!
