We read about the apostles in the gospels, the book of Acts, and in the epistles that follow. We know that James, the brother of John, was martyred by the sword. But how did the rest of them die? What was their ultimate earthly fate? At this post on Randal Rauser’s blog, I learned from “pete” about this source for the ultimate earthly fate of the twelve apostles (along with John the Baptist and Paul).
Their fates are similarly chronicled by William Steuart McBirnie PhD. in his 1973 book of almost 300 pages, The Search for the Twelve Apostles, excerpts of which can be found at this BiblePath.com link.
