εἰς ὑπακοὴν πίστεως: "the obedience of faith"

Says Paul's apostleship is "for the obedience of faith among all the nations" (εἰς ὑπακοὴν πίστεως, eis hypakoēn pisteōs). In 1:5 πίστεως is anarthrous. The phrase recurs at Rom 16:26, in the doxology (Rom 16:25–27). SBLGNT prints that doxology only in its apparatus (WH, Treg and NA28 print it at 16:25–27), RP2018 places it after 14:23 as 14:24–26, and Scrivener's TR has it at 16:25–27.

Several genitive readings are possible: 1. Source: the obedience that springs from faith. 2. Apposition: obedience that consists in faith, so that believing the gospel is itself obeying God. Compare 10:16, οὐ πάντες ὑπήκουσαν τῷ εὐαγγελίῳ, set beside "who has believed?" 3. Objective: obedience to "the faith" as a body of teaching. Abbott-Smith lists Rom 1:5 under the genitive of the object. But "the faith" as doctrine is unlikely when there is no article.

Implies Faith and obedience are distinct, but they are never separated. Paul's mission aims at saving faith in Christ and the life of obedience that flows from it (6:16–17; 15:18).

Uncertain Whether the source reading or apposition is primary. The team leans to source, with apposition close behind, in line with the Exegete. Neither reading turns obedience into a ground of justification (3:28; 4:5).
