The Feast of St. Mark, Evangelist and Martyr
is today. There is information on him here.

The chief points of St. Mark's history are these:—first, that he was sister's-son to Barnabas, and taken with him and St. Paul on their first apostolical journey; next, that after a short time he deserted them and returned to Jerusalem; then, that after an interval, he was St. Peter's assistant at Rome, and composed his Gospel there principally from the accounts which he received from that Apostle; lastly, that he was sent by him to Alexandria, in Egypt, where he founded one of the strictest and most powerful churches of the primitive times.

The points of contrast in his history are as follows:—that first he abandoned the cause of the Gospel as soon as danger appeared; afterwards, he proved himself, not merely an ordinary Christian, but a most resolute and exact servant of God, founding and ruling that strictest Church of Alexandria.

And the instrument of this change was, as it appears the influence of St. Peter, a fit restorer of a timid and backsliding disciple.

The encouragement which we derive from these circumstances in St. Mark's history, is, that the feeblest among us may through God's grace become strong. And the warning to be drawn from it is, to distrust ourselves; and again, not to despise weak brethren, or to despair of them, but to bear their burdens and help them forward, if so be we may restore them.
