The Gospels are, it must be said with gratitude, works of art, the supreme fictions in our culture, narratives produced by enormously influential literary artists who put their art in the service of a theological vision. It is, of course, not uncommon to recognize literary artistry in the Gospels; there is perhaps no more beautiful short story than “The Prodigal Son,” no more moving sentence in all world literature than “I am with you always, until the end of time” (Matt. 28:20) – Randel Helms
Looking at these differences, and there a lot more to point out, one can conclude that either the writers based their stories on different sources of information or that they are literary creations. I believe that since the changes made coincide with an authors particular vision of Jesus Christ that they are most certainly fabrications, molded to fit a theme or to make a point. One could argue, as most Christian apologists do, that the differences are historically compatible. They could argue that, using the centurion as an example, he was both innocent and also the Son of God, so there is no contradiction but rather one author chose to emphasize one point over the other. However, Luke had the centurion say that “certainly this man is innocent” for a reason; Jesus was a prophet in which his people outright rejected him, and it’s structured this way to fit within Luke’s theology of guilt and repentance. Moreover, it’s a climatic phrase for the centurion to say, and therefore has all the hallmarks of a literary creation. I don’t think anyone was recording what the centurion was saying and passed it on through oral tradition; it’s just part of the story. This goes for all the modifications aforementioned. In my view, the editing in it of itself makes it hard to know which is historical and which is not, but an even better argument is that the changes made are too integral to the author’s theme to be anything but literary creations.
