I believe Matthew had multiple incentives to make drastic changes of Mark’s gospel, along with the addition of Q. One of these incentives would be to bring more clarification into his own gospel, where Mark’s gospel was full of a more ambiguous sense. In Mk 6:52, after Jesus had performed a miracle to save the boat from the elements, the apostles had their hearts hardened. A hardened heart shows confusion, this is common throughout Mark’s portrayal of Jesus. In Matthew he adjusts and changes Mark’s gospel completely. Where Mark clearly states the apostle’s confusion, Matthew has the apostles completely accepting that Jesus is indeed the Son of God. This important switcheroo here is that Matthew makes shows his efforts to try and be the disciple with all of the answers. To clear up Mark’s confusion would actually be very important for Matthew. While he is known as the ‘tax payer’ this would obviously give him some definitely needed brownie points with the other disciples. Matthew’s portrayal of Jesus is more of a teacher image, less of the misunderstood miracle man. With less miracles and more teachings Jesus is now more a man that is full of teachings and sermons. In the time period when the Gospel of Matthew was written, it seemed that people living at that time were searching for answers in great need. In a time of Post War, this was a critical period of transition for the Jews, in both political and religious aspects! Matthew could not have been in a better time or place to make changes in the themes of Mark. Matthew not only had the perfect material to unleash, he had an opportunity to clear his name.
