“Here is a major issue for decision. There is really no disputing that Jesus Christ and his apostles, the founders of Christianity, held and taught that the Jewish Scriptures (our Old Testament) were God’s witness to himself in the form of human witness to him. There is no disputing that Jesus Christ, God’s incarnate Son, viewed these Scriptures as his Father’s Word (see how he quotes a narrative comment as the Creator’s utterance in Mt 19:5, citing Gen 2:24); or that he quoted Scripture to repel Satan (Mt 4:3-11); or that he claimed to be fulfilling both the law and the prophets (Mt 5:17); or that he ministered as a rabbi, that is, a Bible teacher, explaining the meaning of texts of which the divine truth and authority were not in doubt (Mt 12:1-14; 22:23-40; and so on); or that he finally went to Jerusalem to be killed and, as he believed, to be raised to life again because this was the way Scripture said God’s Messiah must go (Mt 26:24, 52-56; Lk 18:31-33; 22:37; compare 24: 25-27, 44-47). Nor is there really any disputing (despite skeptical poses struck by some scholars) that “God raised him from the dead” (Acts 13:30), thereby vindicating all he had said and done as right — including the way he had understood, taught and obeyed the Scriptures. So, too, it is clear that the apostles, like their Lord, saw the Scriptures as the God-given verbal embodiment of teaching from the Holy Spirit (Acts 4:25; 28:25; 2 Tim 3:16-17; Heb 3:7; 10:15); and that they claimed, not merely that particular predictions were fulfilled in Christ (compare Acts 3:22-24), but that all the Jewish Scriptures were written for Christians (compare Rom 15:4; 16:26; 1 Cor 10:11; 2 Cor 3:6-16; 1 Pet 1:10-12; 2 Pet 3:16); and that they took over the Old Testament (Septuagint version) for liturgical and homiletical use in the churches alongside their own teaching. For it is also clear that the apostles understood inspiration as the relationship whereby God speaks and teaches in and through human instruction that is given, explicitly or implicitly, in his name. They also saw their own teaching and writing as inspired in just the same sense in which the Old Testament was inspired (compare 1 Cor 2:12; 14:37; 1 Jn 4:6; and so on), so that the later conjoining of their official writing with the Old Testament to form the two-part Christian Bible was a natural and necessary step. None of this is open to serious doubt.
So the decision facing Christians today is simply this: Will we take our lead at this point from Jesus and the apostles?”
