What were the fates of the twelve disciples?

Answer 1

AnswerActs of the Apostles mentions the imprisonment and miraculous release of Peter, but does not say anything about his subsequent death, even though the book was written around the end of the century, long after Peter would have died. A second-century tradition was that he was beheaded, while a later tradition was that Peter was crucified upside down. In fact, the Story in Acts is dubious at best, and the later traditions have no evidence to support them.

At the time of Tertullian and Clement of Alexandria, martyrdom was confined to St. Peter, St. Paul, and St. James. The rest of the disciples were gradually discovered to have been martyred by the more recent Greeks, who prudently selected for the theatre of the disciples' preaching and sufferings some remote country beyond the Roman Empire, where proof to the contrary could never be ascertained. Apart from these traditions, we have no evidence for the fates of the disciples.
