He was with Paul and Barnabas at Antioch, and accompanied them to the Council at Jerusalem (Galatians 2:1-3; Acts 15:2), although his name nowhere occurs in the Acts of the Apostles.
He appears to have been a Gentile, and to have been chiefly engaged in ministering to Gentiles; for Paul sternly refused to have him circumcised, because of Paul's belief that the gospel free one from the requirements of the Mosaic Law.
We find him, at a later period, with 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 saints at Jerusalem sent forward (2 Corinthians 8:6; 12:18).
He rejoined the apostle when he was in Macedonia, and cheered him with the tidings he brought from Corinth (7:6-15). 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 (Titus 1:5).
The last notice of him is in 2 Timothy 4:10, where we find him 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 Crete. He died in AD 107 at about 95 years of age.
