For our textbooks in study of the Gospel of Matthew, you may wish to obtain the following (available at amazon.com) -- particularly the first on the list by Keener. It is not mandatory, but there are recommended readings.
Craig S. Keener. The Gospel of Matthew: A Socio-Rhetorical Commentary. ISBN 978-0-8028-6498-7. This major writing is so thorough and scholarly, as well as inspired and inspiring, that SSC highly recommends you (if possible) add it to your library and follow it throughout this portion of the course.
John Gabel and Charles Wheeler. The Bible as Literature: An Introduction. ISBN-13: 978-0195179071. This is a most excellent textbook explaining literary devices and their use in Scripture. It will be used throughout the rest of this course.
R. T. France. The Gospel of Matthew (The New International Commentary on the New Testament). This commentary is chosen because is is concerned with the " cultural and historical context of first-century Palestine" (amazon). It focuses on Matthew's message alone rather than in its relationship with the other synoptic Gospels.
