🔼The name Demas in the Bible
The name Demas occurs three times in the New Testament and most likely denotes the same man. The apostle Paul mentions Demas twice among his faithful assistants (Philemon 1:24 and Colossians 4:14) but submits no further detail as to the character of this man.
In his second letter to Timothy, the incarcerated Paul wrote that Demas, "having loved this present age" left Paul and went to Thessalonica (2 Timothy 4:10). Most scholars interpret this statement as Paul's complaint that Demas, Crescens and Titus had left him in the lurch, but he may very well have used the word εγκαταλειπω (egkataleipo), meaning to desert or leave behind, to indicate that he considered himself a lost cause and his friends more useful somewhere else (see 2 Timothy 4:12). After all, there's nothing intrinsically wrong with very much loving the world (John 3:16).
