Christians of all kinds resented this representation of Jesus, but were powerless to change it. In the rival Empire of Lietuva, Christianity was not tolerated, the Lietuvan authorities greatly resenting the Christians' refusal to recognize Perkunas and proclaiming him a "false god". Lietuva was known among Christians as "the place where one can still become a martyr," which made it somewhat attractive to certain Christians. Crosstime travelers who visited this Rome and studied its culture became interested in the differences between the Bible used by its Christians and the Bible in this universe. For example, in the Bible used by Christians in the surviving Roman Empire there were only three Gospels, as the Book of John had never been written (and John the Apostle himself possibly never born); the Acts of the Apostles had the same name, but recorded quite different acts; and the Epistles of Paul included several addressed to churches in locations to which the Paul the Apostle never wrote in the history of the Home Timeline.
