My true child (gnhsiwi teknwi). See 1 Timothy 1:2 for this adjective with Timothy. Titus is not mentioned in Acts, possibly because he is Luke's brother. But one can get a clear picture of him by turning to 2 Corinthians 2:13 ; 2 Corinthians 7:6-15 ; 2 Corinthians 8:6-24 ; 2 Corinthians 12:16-18 ; Galatians 2:1-3 ; Titus 1:4 ; Titus 3:12 2 Timothy 4:10 . He had succeeded in Corinth where Timothy had failed. Paul had left him in Crete as superintendent of the work there. Now he writes him from Nicopolis ( Titus 3:12 ). After a common faith (kata koinhn pistin). Here kata does mean standard, not aim, but it is a faith (pistin) common to a Gentile (a Greek) like Titus as well as to a Jew like Paul and so common to all races and classes ( Jude 1:3 ). Koino does not here have the notion of unclean as in Acts 10:14 ; Acts 11:8 .
