 4tn Or “so that the promise could be given by faith in Jesus Christ to those who believe.” A decision is difficult here. Though traditionally translated “faith in Jesus Christ,” an increasing number of NT scholars are arguing that πίστις Χριστοῦ (pisti" Cristou) and similar phrases in Paul (here and in Rom 3:22, 26; Gal 2:16, 20; Eph 3:12; Phil 3:9) involve a subjective genitive and mean “Christ’s faith” or “Christ’s faithfulness” (cf., e.g., G. Howard, “The ‘Faith of Christ’,” ExpTim 85 [1974]: 212-15; R. B. Hays, The Faith of Jesus Christ [SBLDS]; Morna D. Hooker, “Πίστις Χριστοῦ,” NTS 35 [1989]: 321-42). Noteworthy among the arguments for the subjective genitive view is that when πίστις takes a personal genitive it is almost never an objective genitive (cf. Matt 9:2, 22, 29; Mark 2:5; 5:34; 10:52; Luke 5:20; 7:50; 8:25, 48; 17:19; 18:42; 22:32; Rom 1:8; 12; 3:3; 4:5, 12, 16; 1 Cor 2:5; 15:14, 17; 2 Cor 10:15; Phil 2:17; Col 1:4; 2:5; 1 Thess 1:8; 3:2, 5, 10; 2 Thess 1:3; Titus 1:1; Phlm 6; 1 Pet 1:9, 21; 2 Pet 1:5). On the other hand, the objective genitive view has its adherents: A. Hultgren, “The Pistis Christou Formulations in Paul,” NovT 22 (1980): 248-63; J. D. G. Dunn, “Once More, ΠΙΣΤΙΣ ΧΡΙΣΤΟΥ,” SBL Seminar Papers, 1991, 730-44. Most commentaries on Romans and Galatians usually side with the objective view.

sn On the phrase because of the faithfulness of Jesus Christ, ExSyn 116, which notes that the grammar is not decisive, nevertheless suggests that “the faith/faithfulness of Christ is not a denial of faith in Christ as a Pauline concept (for the idea is expressed in many of the same contexts, only with the verb πιστεύω rather than the noun), but implies that the object of faith is a worthy object, for he himself is faithful.” Though Paul elsewhere teaches justification by faith, this presupposes that the object of our faith is reliable and worthy of such faith.
