Matthew's Gospel is the most significant Jewish-Christian document of the New Testament. Ulrich Luz both outlines and elucidates the story told in the Gospel, emphasizing its focal points: the Sermon on the Mount, the miracles, the renunciation of possessions, and particularly the theology of judgment by works, an idea that represents both a challenge, in its quest for a church set apart from non-Christians by deeds alone, and a burden, through its traumatic origin in the breach between Matthew's community and the Israelite majority.
A solid introduction to Matthew which relies a bit too heavily on en vogue scholarly theories and redaction criticism, but still quite useful. Luz's pastoral and practical tone are also helpful, emphasizing Matthew's (and Jesus'?!) focus on actions rather than just doctrine.
