Here's a blurb about it from the publisher:
"It is now widely said that the four Gospels rose to prominence only after a long battle within early Christianity, a battle finally won in the fourth century, after the establishment of the Church by Constantine the Great. In Who Chose the Gospels? Charles E. Hill demolishes this claim, providing a more historically accurate, alternative account of how the Church came to acknowledge four, and only four, narratives of the life of Jesus. Hill offers not only an informed critique of recent, overtly "political" readings of early Christian history, but also a more nuanced analysis of how and why, out of all the Gospels written in the early centuries of the Church, just these four "made it" into the Bible. In fact, the author shows that despite the profusion of Gospels, there was wide agreement among church leaders, in diverse regions of the empire, at least from the second century onward, as to the authority of Matthew, Mark, Luke, and John. Thus it was not a conspiracy but common consensus that determined the books of the New Testament."
