St. Martin I

St. Martin I became the 74th pope in 649, but he did not have imperial approval. During the Lateran Council, St. Martin I condemned Monothelitism, the belief that Christ had no human will. The emperor, who had ruled that no one talk about Christ’s will at all, had St. Martin I arrested and tortured. The pontiff died from injuries sustained in his imprisonment around the year 655. St. Martin I is considered the last martyred pope.
