Jesus Justus
Jesus Justus was one of several Jewish Christians in the church at Rome mentioned by Paul the Apostle in the greetings at the end of the Epistle to the Colossians .
It is generally thought that Paul wrote Colossians while in prison in Rome most likely during AD 50s. Of those with Paul, Justus, Aristarchus, and Mark, the cousin of Barnabas, are said in the letter to be “of the circumcision”, that is, Jewish and to have "proved a comfort to me."
The name Jesus was not uncommon at the time of Jesus of Nazareth, as it was a form of the Old Testament name Joshua. The extra name "Justus" was likely to distinguish him from his Master, Jesus Christ.
Jesus Justus is not mentioned in a similar passage in Philemon whereas Aristarchus, Epaphras and Mark are again explicitly named by Paul.
