The Lord's Envoy said:
"The first Christian's did not have a complete Bible." How does one respond to that from the perspective of Scripture Alone?
My Brother in Christ,
The majority of the first Christians were Jewish, and had grown up with the books of the TanakhThe Jewish Old Testament. A book that most of them knew very well. Looking at the situation from the perspective of approximately 2,000 years. It is easy to see that there was a lot that they could learn about Jesus the Christ from the Messianic prophecies of the OT. Enough to keep them busy for quite some time.
Then consider that Acts tells us several more things: Acts 2:41-47 "41 So then, those who had received his word were baptized; and that day there were added about three thousand souls. 42 They were
continually devoting themselves to the apostles' teaching and to fellowship, to the breaking of bread and to prayer. 43 Everyone kept feeling a sense of awe; and many wonders and signs were taking place through the apostles. 44 And all those who had believed were together and had all things in common; 45 and they began selling their property and possessions and were sharing them with all, as anyone might have need. 46
Day by day continuing with one mind in the temple, and breaking bread from house to house, they were taking their meals together with gladness and sincerity of heart, 47 praising God and having favor with all the people And the Lord was adding to their number day by day those who were being saved.
They were devoting themselves DAILY to the Apostle's teaching and fellowhip. What were the Apostles teaching them? Everything that they had learned from Jesus, and everything that the Holy Spirit was adding to that knowledge.
As the Apostles went out from Jerusalem this practice went with them. Even Paul, Apostle to Kings and Gentiles, went first to the Jewish synagoges to teach, for there he could find ready audiences who already knew the Scripture of the Old Testament as well as the promises of the coming Messiah. In most of the churches that Paul planted the Pastor's set up to teach the new Christians were often some of the strongest Jewish converts to Christianity who had a strong background in the Old Testament.
This was more than enough to point out the need for redemption and a Kinsman-Redeemer to pay the price for salvation. The whole of the Old Testament pointed to Jesus. The crying shame today is that too many Pastors don't see and understand that truth. If more pastors feed their flock from the examples and truths of the Old Testament our churches wouldn't be so anemic and apathetic. Remember, these things were written for our example.
By the time the early Christians, especially the Jewish converts, had matured enough to understand the teachings about Christ in the Old Testament, the Epistles were being circulated among the churches and the Gospels were being written. Read verse 47 again. G-d's plan and program for the church worked just fine thank you. At least till the church growth movement came around with their idea for a "better" plan.
