The message of Jesus was that he was the fulfillment of all the promises which God had made in time past. He was the seed of the woman who would bruise the head of the serpent, or sin. He was the seed of Abraham who would inherit the land of Israel for ever. He was the sacrificial lamb that the Law of Moses prophesied would have his blood poured out upon the altar for the atonement of the sins of the people. He was the King who would sit upon the throne of David. He was the Word made flesh. He was the fulfillment of all the promises God made to mankind.
Therefore Christadelphians teach:
XI. That the message he delivered from God to his kinsmen the Jews, was a call to repentance from every evil work, the assertion of his divine sonship and Jewish kingship; and the proclamation of the glad tidings that God would restore their kingdom through him, and accomplish all things written in the prophets.
The Jews could not understand this. They were under the control of the Roman Empire; the Messiah they were looking for would break the Roman yoke. The lamb-like characteristics that Jesus taught were nothing in which they were interested. They envied his power and his popularity with the people, and finally, put him to death on the cross. Therefore, Christadelphians teach:
XII.--That for delivering this message, he was put to death by the Jews and Romans who were, however, but instruments in the hands of God, for the doing of that which He had determined before to be done--namely, the condemnation of sin in the flesh, through the offering of the body of Jesus once for all, as a propitiation to declare the righteousness of God, as a basis for the remission of sins. All who approach God through this crucified, but risen, representative of Adam's disobedient race, are forgiven. Therefore, by a figure, his blood cleanseth from sin.
