Towards the end of the 19th century and beginning of the 20th century, it was becoming more popular in German scholarship to connect the origins of Christianity with heavy influence from the mystery cults, if not labeling Christianity itself as a mystery cult. This trend was partly the result of the increasing growth of critical historical analysis of Christianity's history, as exemplified by David Strauss's "Das Leben Jesu" (1835–6) and the secularizing trend among scholars that sought to derive Christianity from its pagan surroundings. Scholars, for example, began attempting to derive Paul's theology from a Mithraic mystery cult in Tarsus, even though no mystery cult existed there nor did a Mithraic mystery cult exist before the end of the 1st century. The attitudes of scholars began to change as Egyptology continued emerging as a discipline and a seminal article published by Arthur Nock in 1952 that noted the near absence of mystery terminology in the New Testament. While some have tried to tie the origins of rites in Christianity such as baptism and the Eucharist to mystery religions, it has been demonstrated that the origins of baptism rather lie in Jewish purificatory ritual and that cult meals were so widespread in the ancient world that attempting to demonstrate their origins from any one source is arbitrary. Searches for Christianity deriving content from mystery religions has also been unsuccessful; many of them (such as the mysteries of Eleusis and Samothrace) had no content but rather limited themselves to showing objects in initiation.
