There is an on-going debate about the relationship of the first reading and the gospel. Some argue that the complementary stream relegates the Hebrew Scriptures to a role of prolegomenon to the New Testament and does not respect the integrity of the Hebrew texts. Others maintain that it is possible to respect the integrity of the Hebrew texts even while using the complementary stream.
As a long-time participant in the Metro Vancouver Jewish-Christian Dialogue I have come to believe that the complementary approach honours both the continuity and the distinct character of God's revelation to the Jewish people and the Christian movement. It is, after all, the approach taken in the Revised Common Lectionary for the lectionary texts from the Reign of Christ to Trinity.
