Let's say that some time in the mid-to-late 14th century, the Divine Comedy by Dante Alighieri is accepted by the Church to be the last book of the New Testament after the Book of Revelation. Dante himself isn't considered a prophet, but he is considered to be divinely inspired to collect and summarize what Christianity professes about the afterlife. The Comedy's version of the afterlife is also made the official standpoint of the Church about what comes after death.
How do you think would this influence the development of European culture and religion in the coming centuries? Would it butterfly away the Reformation and maybe the Industrial Revolution and make more aspects of pre-Renaissance medieval culture survive longer? How would the present day look like in this TL?
