In the Christian New Testament, Saint Titus, (a common Roman first name) was a companion of Paul of Tarsus, mentioned in several of Paul's epistles, including the Epistle to Titus. Titus was with Paul and Barnabas at Antioch and accompanied them to the Council of Jerusalem, although his name nowhere occurs in the Acts of the Apostles.
He appears to have been a Gentile – for St. Paul sternly refused to have him circumcised, because Paul believed Christ's gospel freed believers from the requirements of the Mosaic Law – and to have been chiefly engaged in ministering to Gentiles. At a later period, Paul's Epistles place him with St. Paul and Timothy at Ephesus, whence he was sent by Paul to Corinth for the purpose of getting the contributions of the church there in behalf of the poor Christians at Jerusalem sent forward. He rejoined the apostle when he was in Macedonia, and cheered him with the tidings he brought from Corinth. After this his name is not mentioned till after Paul's first imprisonment, when we find him engaged in the organization of the church in Crete, where the apostle had left him for this purpose. The last notice of him is in , where he appears with Paul at Rome during his second imprisonment. From Rome he was sent into Dalmatia, no doubt on some important missionary errand. The New Testament does not record his death.
According to church tradition, Paul ordained Titus Bishop of Gortyn in Crete. He died in the year 107, aged about 95.
The feast day of St Titus was not included in the Tridentine Calendar. When added in 1854, it was assigned to 6 February. In 1969, the Roman Catholic Church assigned the feast to 26 January so as to celebrate the two disciples of Paul the Apostle, Titus and Timothy, on the day after the feast of the Conversion of St. Paul. The Evangelical Lutheran Church in America celebrates these two together with Silas on the same date (see Calendar of Saints).
However, other biblical passages seem to dispute this theory, namely 2 Timothy, an epistle to Timothy, which states that Titus has gone to Dalmatia (2 Timothy 4.10).
