A.T. Robertson Commentary 1 Timothy 1:2

"unto Timothy, my true child in faith: Grace, mercy, peace, from God the Father and Christ Jesus our Lord." — 1 Timothy 1:2 (ASV)

True (γνησιω). Legitimate, not spurious. Old word from γινομα, but Pauline only in N.T. (2 Corinthians 8:8; Titus 1:4). In Php 2:20 the adverb γνησιως occurs and of Timothy again.

Christ Jesus (Χριστου Ιησου). So twice already in verse 1 and as usual in the later Epistles (Colossians 1:1; Ephesians 1:1).
