Introduction
1. Life of St. Mark. Mark, i.e. Marcus, a common Roman praenomen, was the name by which the evangelist was usually known in Gentile and Christian circles. His original Jewish name was John (Acts 12:12). As St. Mark was the cousin of St. Barnabas, it is plausibly suggested that, like him, he was a Levite, settled in Cyprus (Colossians 4:10). An ancient tradition states that 'he ministered in the priesthood in Israel, being according to the flesh a Levite'; and that 'after his conversion, he amputated his finger that he might be rejected from the priesthood.' Certainly in early times he bore the title of Koldbodactylus, i.e. 'maimed in the finger,' but it is possible that the loss of his finger was due to accident or congenital malformation.
According to an unnamed ancient presbyter who lived in the apostolic age, St. Mark was not a follower of Jesus, but a convert of St. Peter. The presbyter's account is confirmed by certain indications in the NT. It is clear from the Acts that the mother of St. Mark, whose name was Mary, was living in Jerusalem not long after the crucifixion (Mark 12:12), She was a woman of some wealth, occupying her own house, and employing several servants or slaves. St. Peter probably lodged with her (Mark 12:12); at any rate, her house was used as a church, and formed an important Christian centre. St. Peter, being thus an inmate of the same house with St. Mark, was enabled to convert him, and afterwards spoke of him as 'Mark my son,' i.e. my convert (1 Peter 5:13): cp. 1 Corinthians 4:15.
At the time of the crucifixion St. Mark, though not a convert, was probably already an enquirer. In Mark 14:51 mention is made of a certain young man who was so much interested in the fate of Jesus, that when the arrest took place, he hastily rose at midnight and followed the procession. This picturesque but unimportant incident is recorded by no other evangelist, and since the name is suppressed, it is at least probable that the young man was St. Mark himself. If this is correct, it would appear that St. Mark, though not technically a 'hearer' of Jesus, was at least a witness of some of the events of Holy Week.
It is probable that St. Mark, as a convert of St. Peter, sympathised more with the Jewish party led by that Apostle than with the Gentile party of St. Paul. This probably gives the true explanation of the distressing incident related in Acts 13:13. Barnabas and Paul had brought Mark from Jerusalem to Antioch (Acts 12:25), and had chosen him to act as their 'minister' (i.e. ministerial assistant for such work as catechising and baptising converts, which was not ordinarily done by the Apostles in person, 1 Corinthians 1:14) on their first missionary journey (Acts 13:5). But after passing through Cyprus, Mark left them and returned to Jerusalem (Acts 13:13). The causes of this action were partly personal. St. Mark, it seems probable, resented the growing ascendency of St. Paul over his cousin St. Barnabas, but most of all he disliked St. Paul's treatment of uncircumcised Gentiles as the equals of circumcised Jews. He therefore preferred to return to the thoroughly Hebrew Church of Jerusalem. The breach was not healed even by the Council of Jerusalem, which occurred some three or four years later. Soon after that event, when Barnabas proposed to Paul to take Mark on another missionary journey, St. Paul refused, and a warm dispute parted the two friends, St. Mark accompanying St. Barnabas to Cyprus (Acts 15:37). Ultimately, however, the breach between St. Mark and St. Paul was healed. St. Paul, writing from his prison in Rome (61 a.d.), speaks of him in affectionate terms as a companion and fellow-labourer (Philemon 1:24; Colossians 4:10). A few years later, writing shortly before his death (66 a.d.), he speaks of him as 'profitable to me for the ministry,' or, rather, 'profitable to me for ministering,' and bids Timothy bring him with him (2 Timothy 4:11).
But it is as the companion of St. Peter that St. Mark is best known to ecclesiastical tradition. According to the apostolic presbyter before referred to, St. Mark became the 'interpreter' of St. Peter, probably after the release of St. Paul from his first imprisonment. St. Peter, in all probability, was not a very good Greek or Latin scholar. Preaching in Aramaic, he required the services of an interpreter to translate his sermons clause by clause into Greek or Latin, as the case might be, and also to conduct his correspondence. The relation of St. Mark to St. Peter as his 'interpreter' is confirmed by 1 Peter, written from Rome, where St. Peter says, 'The church that is at Babylon (i.e. Rome), elected together with you, saluteth you; and so doth Marcus my son' (1 Peter 5:13).
After the martyrdom of St. Peter (cirMark 67 a.d.) little is known of the life of St. Mark. Tradition makes him the founder and first bishop of the important Church of Alexandria. He is not spoken of as a martyr by any writer earlier than the 5th cent. He is commemorated by the Church on April 25th.
