True (gnhsiwi). Legitimate, not spurious. Old word from ginomai, but Pauline only in N.T. ( Philippians 4:3 ; 2 Corinthians 8:8 ; Titus 1:4 ). In Philippians 2:20 the adverb gnhsiw occurs and of Timothy again. Christ Jesus (Cristou Ihsou). So twice already in verse Philippians 1 and as usual in the later Epistles ( Colossians 1:1 ; Ephesians 1:1 ).
