While both Matthew and Paul quoted extensively from Tanach in order to support their teachings, only Paul would successfully persuade his audience.
The Book of Matthew was written for a Jewish audience. As a result, Matthew’s mission largely failed among the people he sought to convert because the Jews were repelled by his wild exploitation of Tanach. Paul’s venture, on the other hand, was enormously successful. The minister to the gentiles was preaching to audiences that were completely illiterate, and lacked the ability to discern between genuine Judaism and Bible-tampering.
Rabbi Singer demonstrates how Paul corrupted the Jewish scriptures in order to both undermine the Torah, and advance his new, sweeping doctrines that would lay the foundation for Christian theology.
