Stauffer was the son of a Mennonite preacher born and raised in Worms. After attending the local grammar school, he studied Protestant theology at the universities of Halle, Berlin and Tübingen from 1921-1925. He then entered the service of the Mennonite churches in Hamburg and Altona. He converted to the Evangelical Church in 1928, and became assistant pastor of the Provincial-Saxon church. The New Testament scholar Ernst von Dobschütz appointed him the faculty assistant in Halle, where he graduated in 1929. He became a lecturer there in 1930. In the 1930s Stauffer was appointed professor of New Testament Studies and director of Ancient History Studies at the University of Bonn. Although he evidently never joined the Nazi Party, he was a long-time and leading proponent of the "German Christian" movement, which attempted to align German Protestantism with the Party's antisemitic and Führerprinzip ideological principles, and he has frequently been accused of "Nazi activities." Stauffer argued that it was the duty of the theological faculty to promote a relationship of trust between the church and state and "called on the theological faculties not to engage in politics, but to strengthen, through their theological work, the politische Spannkraft of the German Volk; the unity of the German Volk cannot exist without Jesus Christ, he wrote." He also promoted physical education as part of a theological education. One of Stauffer's early contributions to the movement was his 1933 publication Unser Glaube und unsere Geschichte: Zur Begegnung zwischen Kreuz und Hakenkreuz. His relationship with the Nazi state became ambivalent, and he was removed from his post as vice-dean of the faculty of Bonn university in January 1943 for anti-fascist statements in a lecture on "Anthony and Cleopatra." After the war he escaped close scrutiny by the Allied authorities on "the naive assumption among Allied authorities... that those who had expertise in rabbinical texts must have been sympathetic to Judaism, or at least uninvolved in Nazi activities." Stauffer was elected Dean of the Faculty of Protestant Theology and restored the Bonn faculty restore, but resigned at the first meeting of the Faculty on June 5, 1946, over questions of his wartime activities. Evidently after a review of his writings, he was cleared. On December 8, 1947, however, he advised the rector that he would follow a call to Erlangen in 1948 to a newly founded chair of New Testament Studies. In 1957 he admitted the anti-semitic ideas of the German Christians by stating: "The primary role of Jesus research is clear: De-Judaizing the Jesus tradition." Stauffer became professor emeritus in 1967. Stauffer had two daughters and two sons. His third child followed him in his theological career. His son Dietrich became a Professor of Theoretical Physics at the University of Cologne.
He undertook much research into the relationship between the Roman sources and early Christianity. He showed that the Easterliturgydoes not follow the Gospel but the funerary ritual of Julius Caesar and that the Clementia Caesaris was the pre-Christian forerunner of Christ's forgiveness.
Universalism
Stauffer was a Christian universalist, believing that ultimately all people would be saved. He believed that God's irresistible grace and will are destined to overcome even the most obdurate opposition. He also taught that divine punishment after death was real, but that it was not arbitrary or vindictive, but remedial and limited as to duration, essentially Purgatory.
Martyrdom in Christian theology
In 1933, Stauffer put forth a thesis regarding the role of martyrdom in Christian theology. According to Stauffer, in the period of post-canonical Judaism a new viewpoint impressed itself on the then flourishing apocryphal literature: the idea that suffering and martyrdom for one's faith are the very meaning of the happenings of history, for a double reason: they represent a causal necessity in the great fight between the divine and the satanic order. The great Adversary does not allow a pure realization of God's plan, at least not in this present aeon or world period. Such suffering, however, serves at the same time a very great purpose: it ushers in the new aeon. Death becomes victory, martyrdom is an expiating sacrifice, and Satan will be overcome only by such nonresistant suffering. That was the teaching of Daniel 3 and of the Second and Third Book of the Maccabees. In short, the apocalyptic, pre-Christian literature offers this double justification of martyrdom: causally it is inescapable, and teleologically it is absolutely meaningful. The New Testament continued this apocalyptic trend even further; the Cross becoming the very center not only of salvation but also the vindication of all martyrdom for conscience' sake. In fact the idea of Nachfolge or discipleship would almost be without meaning if it were not connected with such earthly tribulations. The believer's conflict with the "world" is the surest indication that the disciple is true to the master, testifying for another reality and preparing for the coming of the kingdom. Two figures of speech soon became generally accepted: the disciple must become a "soldier" of Christ who "fights the good fight" to the bitter end, and secondly, baptism is called death just as death is a sort of baptism by blood.
