[1][2] He married a teacher named Mary M. Wageman on April 28, 1898;[3] she spoke in the pulpit on occasion and also wrote for The Brethren Evangelist.

[4] Bauman and Stover first met at an evangelistic campaign in Sunnyside, Washington in 1911, where Brethren leader and Grace Seminary co-founder Alva J. McClain was converted to Christianity.

[2] In 1900 Bauman began a pastorate at the First Brethren Church of Philadelphia, a place where his interest in foreign missions and eschatology would bloom.

[9] Bauman's interest in eschatology was greatly impacted by a well known Brethren premillennialist and through the grieving process of losing his oldest son.

In his eulogy of Bauman, longtime Long Beach Brethren Church assistant pastor Alan S. Pearce summarizes the experience.

[5]While in Philadelphia Bauman wrote the first edition of his magnum opus The Faith Once for All Delivered unto the Saints, at slightly over 100 pages details his traditional Brethren beliefs along with his developed interest.

Stout, held an evangelistic tent meeting on the southeast corner of Tenth Street and Walnut Avenue, where seventy-one individuals converted to Christianity and forty-nine expressed interest to become members of a Brethren Church in Long Beach.

He fulfilled several evangelistic campaign commitments that winter and returned as pastor on March 2, 1913 as a church building was being built, which was dedicated on July 20 of that year.

He wrote over ten books, contributed regularly to magazines in both the fundamentalist and Brethren perspectives, and spoke at numerous churches and conferences.

His method have since been repeated by authors Hal Lindsey of The Late Great Planet Earth fame and Tim LaHaye, co-author of the Left Behind series.

He wrote countless letters, mostly to missionaries encouraging their work and to fellow pastors concerning both personal regards and issues within the Brethren Church.

The fundamentalist's classic dispensationalist belief largely disregarded the Sermon on the Mount as a law for an earlier age, while the traditional Brethren statement "the New Testament is our Rule of Faith and Practice" placed a high emphasis on this passage in Matthew 5-7.

Bauman held strongly to beliefs (and concerns) of other early twentieth century fundamentalist, being deeply against classic liberalism and consumed with end times prophecy.

Several of Bauman's fundamentalist perspectives did create strong disagreement among many of his Brethren Church peers and along with the events at Ashland College brought about the denominational split of the late nineteen thirties.

"[14] At the height of conflict between "Ashland" and "Grace" Brethren groups, Bauman wrote: We hold in common with our Brethren of The Grace Seminary Group that The Sermon on the Mount, coming from the lips of the incarnate God, is the highest, holiest, purest, most perfect law that ever has fallen, or ever will fall, upon ears of men.
