1:15 firstborn. Christ is “the firstborn,” not in the sense that He ever came into existence from a prior condition of non-existence, but rather as eternally proceeding from the Father, the only begotten Son, always manifesting the Father. This truth can be called the doctrine of eternal generation. He is from eternity to eternity in relation to the Father as a Son. Some are sons of God by creation (e.g., angels; see Job 1:6), and we can become sons of God by adoption (e.g., Romans 8:14-15), but He is the Son, by eternal generation (or eternal relation) the only-begotten of the Father. He also has the right of inheritance of the firstborn (Hebrews 1:2) and is “the firstborn from the dead” (Colossians 1:18).
