Feast of St. Mark, evangelist

An intimate friendship existed between Mark and Peter; he played the role of Peter's companion, disciple, and interpreter. According to the common patristic opinion, Mark was present at Peter's preaching in Rome and wrote his Gospel under the influence of the prince of the apostles. This explains why incidents which involve Peter are described with telling detail. Little is known of Mark's later life. It is certain that he died a martyr's death as bishop of Alexandria in Egypt. His relics were transferred from Alexandria to Venice, where a worthy tomb was erected in St. Mark's Cathedral.
The Gospel of St. Mark, the shortest of the four, is, above all, a Roman Gospel. It originated in Rome and is addressed to Roman, or shall we say, to Western Christianity. Another high merit is its chronological presentation of the life of Christ. For we should be deeply interested in the historical sequence of the events in our blessed Savior's life.
Furthermore, Mark was a skilled painter of word pictures. With one stroke he frequently enhances a familiar scene, shedding upon it new light. His Gospel is the "Gospel of Peter," for he wrote it under the direction and with the aid of the prince of the apostles. "The Evangelist Mark is represented as a lion because he begins his Gospel in the wilderness, `The voice of one crying in the desert: Make ready the way of the Lord,' or because he presents the Lord as the unconquered King."
