Harmony of the Gospels is often talked about and has been written about, beginning in the second century. The disciples and Y’shua went around without notes or scrolls, with no need for constant word for word messages, so similar messages have variants. Because of those variations, a number of copiers of the earliest manuscript of the New Testament made changes in order to harmonize, to bring the Gospels into complete agreement. Around the middle of the second century, Tatian made the ultimate harmony by combining all four Gospels into one document called Diatessaron, Through the Four. There certainly is a great deal of agreement among the Gospels, each one preserving the basic elements of our Christian faith. Many of the differences between Gospels are there because Y’shua taught similar messages in different settings. In His many travels through Israel, He spoke to different crowds, sometimes using parables and other teachings that He had used before. Two examples of this are from the Sermon on the Mount.
