16:25–27 The authenticity of this closing doxology is questioned by some on the grounds of its length, its emphasis on mystery, and its textual history (it is found at different points in the letter, or even omitted altogether in various ancient manuscripts). There is, however, a certain appropriateness about its length, coming at the end of a letter like Romans. Its themes draw to a fitting conclusion much that has already been said. In particular, Paul draws attention to his own teaching of the gospel (2:16; cf. 1 Thess. 1:5; 2 Tim. 2:8) and its power to edify (1:11), to the revelation of God’s mystery (11:25; cf. Eph. 3:2–6), to faith and obedience among the nations (1:5), and to the wisdom of God in redemption (11:33; cf. Eph. 3:10–12).
