Part 2b on my series on the sufficiency of the Scripture as the sole, infallible authority for Christian faith and life. Part #1 was an introduction to set the stage. Part #2a was the first part of what different books of the New Testament have to say on the matter.

Romans

Paul grounded the Gospel of Jesus Christ in the authority of the OT Scriptures. He tied the Gospel to that which God “promised beforehand through his prophets in the holy Scriptures,” (Rom 1:2). The Book of Romans is literally saturated with references to OT Scriptures to make theological points,^[1] far more so than a brief biblical theology here can hope to demonstrate. Once again, Paul does not base his arguments on philosophy or tradition – he bases them on Scripture.

It is not the hearers of the law who are justified, but the doers (Rom 2:12-29). None are righteous (Rom 3:9-18); “there is no fear of God before their eyes,” (Rom 3:18). Knowledge of the OT law brings about conviction and knowledge of sin (Rom 3:19-20; 4:15; 7:7-25). The Law and Prophets bore witness to Christ (Rom 3:21-22). Abraham was justified by faith (Rom 4). We are dead in Adam but alive in Christ (Rom 5:12-21). God’s sovereignty in election is grounded in His corporate election of Israel and the individual, single election of individuals (Rom 9).

Israel refuses to respond to the present provision of salvation through Jesus Christ (Rom 10), and Paul bolstered his argument by citing examples of Israel’s previous rebellion (Rom 10:18-21). Gentiles have been grafted into the promises given to Abraham (Rom 11), “so as to make Israel jealous,” (Rom 11:11). Her rejection is not final and her restoration is assured. Paul’s appeal for Christians to present themselves as living sacrifices (Rom 12:1) is rooted in the OT concept of a sacrifice to God. Christ came to the Jews in the form of a servant “in order to confirm the promises given to the patriarchs,” (Rom 15:8-9).

Paul presents the new doctrine he received from Christ (Gal 1:12) as explicitly progressive revelation. This gospel and preaching of Jesus Christ, in complete accord with all which has come before it, is a “revelation of the mystery that was kept secret for long ages, but has now been disclosed and through the prophetic writings has been made known to all nations, according to the command of the eternal God,” (Rom 16:25-26).

1 Peter

Peter writes his epistle to Jewish Christians (1 Pet 1:1 – “elect exiles of the Dispersion”), demonstrating a clear connection in his mind between the OT and the Gospel of Jesus Christ. He stated that Christ fulfilled the OT prophesies.^[2]

The prophets prophesized about the grace of God in salvation in Jesus Christ (1 Pet 1:10). These OT prophets sought to discern when the prophesy of Christ’s sufferings and subsequent glories would come to pass (1 Pet 1:11). It was revealed to these great men, presumably through the Spirit, that these prophesies were intended for a future time. Peter identified that time period as “now,” or the dispensation of grace in the church age.^[3] The OT prophesies take on clearer, concrete and unmistakable meaning in light of the progressive revelation of the Gospel of Jesus Christ (1 Pet 1:12).

It was revealed to them that they were serving not themselves but you, in the things that have now been announced to you through those who preached the good news to you by the Holy Spirit sent from heaven, things into which angels long to look (1 Pet 1:12).

The context of 1 Pet 1 is that his readers could rejoice in their sufferings even though they could not see exactly how or when their present trials would end. Just as the OT prophets had limited understanding of their own prophesies, they trusted God to sovereignty work out all things according to good (Rom 8:28). God’s answer to Habakkuk’s plea for understanding of God’s ways was to live by faith (Hab 2:4). In the midst of suffering (1 Pet 1:6), it is very significant that Peter points his readers to Scriptures as the source of assurance. Several conclusions can be drawn:

1. God has spoken propositionally to His people in a concrete fashion.
2. Peter points to the Scriptures as the sole source of God’s revelation to men. He bases his subsequent call to be holy in a decidedly unholy world (1 Pet 1:13 – “therefore”) on the assurance of salvation and glorification in Christ, which was prophesied of in the OT and disclosed more completely by Peter and the other apostles.

Peter quotes the OT to make theological points, underscoring the authority of the OT.^[4] He quoted from Isaiah 40:6, 8 (1 Pet 1:24-25) and stated “the word of the Lord remains forever.” He concluded by noting “and this word is the good news that was preached to you,” (1 Pet 1:25b). Peter describes the role of the Christian in terms of Israel’s covenant responsibility similar to Ex 19:5-6 (1 Pet 2:9).

James

James also writes his epistle to Jewish Christians (Jas 1:1). His theology is steeped in the OT Scriptures. Without his unwavering reliance upon them as an infallible revelation from God, James could not have written his epistle. His theology of God’s character is one of holiness (Jas 1:13), and perfectly in tune with the OT description of His character (Lev 11:45, 19:2; Ps 99:9).

Pure religion, or piety,^[5] consists of proper conduct and character. James’ example of proper religious conduct is to “visit orphans and widows in their afflictions,” (Jas 1:27), an admonition which is soaked in the context of the OT law regarding social justice (Ex 22:22; Deut 14:29). His exhortation to proper character is to “keep oneself unstained from the world,” (Jas 1:27), which likewise has its roots in the OT command for Israelites to remain separate and uncontaminated by the pagans round about them (Lev 18:24-19:2).

James’ overarching point is to contrast mere ritualistic observances with actual reverence for God; to illustrate what “religion that is pure and undefiled before God” (Jas 1:27) really is. It is merely a stepping stone from here to a contrast between mere outward circumcision and a true circumcision of the heart (Deut 10:12-16).

James quoted repeatedly from Scripture to condemn the sin of partiality (Jas 2:8, 11). James used the example of both Abraham and Rahab to make the point that faith without works is dead (Jas 2:14-26). He quoted Proverbs 3:34 to emphasize the need for humility and separation from worldliness (Jas 4:1-6). He pointed to the example of Job and exhorts his readers to have patience in the midst of suffering and trials (Jas 5:10-11). James cited the fervent prayers of Elijah as he exhorted his readers to pray diligently for one another (Jas 5:16-18).

Jude

Like his brother James, Jude’s theology simply would not exist without the OT Scriptures. Jude wrote of “the faith that was once for all delivered to the saints,” (v. 3). This faith Jude spoke of was the body of truth taught by the apostles.^[6] This underscores the progressive nature of God’s revelation, and is perfectly harmonious with Peter’s (1 Pet 1:10-12), Paul’s (Eph 3:1-13) and the writer to the Hebrew’s (Heb 1:1) comments in their own epistles on this point.

Jude noted the presence of false teachers who “long ago were designated for this condemnation” (v. 4). This refers to previously written prophesies regarding the doom of apostates (e.g. Isa 8:19-22; Jer 5:13-14).^[7]

Jude notes God’s righteous pattern of punishing those who apostatize from the true faith, such unbelieving Israelites, angels and the inhabitants of Sodom and Gomorrah and the surrounding cities (v. 5-7). These “serve as an example by undergoing a punishment of eternal fire,” (v. 7). Jude then moves to his present day and condemns contemporary false teachers of these very sins! (v. 8). He mentions the archangel Michael, compares the false teacher’s way to that of Cain and Balaam, and compares their eventual end to that of Korah (v. 11). Jude also accurately puts Enoch as the “seventh from Adam,” (v. 14).^[8]
