Such opposition, however, is ironic in the context of church history. For American Protestants regularly called their clergy "Father" 200 and 300 years ago, and some continued to do so a century ago. And during the same years, Protestants addressed venerated women in their churches as "Mother."
The title "Father" was used in four ways in addressing clergy (see my article, "Fathers and Brethren," Church History [September 1968], pp. 298-318). In early America "Father" was a title of respect for elderly men. Although, for example, "Mister" (the designation of a gentleman and a college graduate) was the normal title for Puritan clergy in colonial New England, Congregationalists. Baptists, Methodists and German Reformed commonly addressed older ministers as "Father" well into the 19th century.
Furthermore, Protestants also employed the title for younger ministers who influenced Christian commitment and served as spiritual fathers. This usage is evident in the correspondence between early American ministers and their theological students. The journals of Methodist circuit riders as well as the records of Protestant missions to Indians and seamen also indicate this usage. Herman Melville, for example, based his character Father Mapple -- the whaleman-chaplain in Moby Dick -- on Father Edward Thompson Taylor, the Methodist pastor of Boston’s Seamen’s Bethel.
Protestants of earlier centuries also addressed founders of denominations and religious communities as "Father." American Methodists, for example, referred to John Wesley not only as "Mr. Wesley" but also as "Father Wesley." Following the custom in both genders, the Shakers called their matriarch ‘‘Mother’’ and their male leaders "Father."
Closely related was the custom of calling missionary pioneers "Father." In the 19th century, Presbyterian, Baptist, Congregationalist, German Reformed, Methodist and Universalist missionaries were given the title throughout the New South and West. And American Lutherans used "Father" for their pioneer pastors, their first missionary to India, and their patriarch, Father Henry Melchior Muhlenberg.
Few in Protestant churches of earlier generations would have seen a theological problem in addressing spiritual fathers, founders or missionary pioneers as ‘Father." Just as the author of I John addressed as "fathers" the elderly who were advanced in the knowledge of Christ (I John 2:13-14), so Protestant churches applied the title to experienced ministers who had been long in the service of the church. "Fathers and Brethren" sat in ecclesiastical assemblies, and in the New Testament "Father" denoted the difference between generations.
Moreover, if calling clergy "Father" had violated biblical norms, the Christian Church and Disciples of Christ surely would have opposed it, for these groups were formed in an attempt to restore not only the doctrine and practice of primitive Christianity, but also its very nomenclature. Warren Stone’s motto was "Bible names for Bible things." And Thomas and Alexander Campbell stood on the phrase, "Where the Bible speaks, we speak: where it is silent, we are silent." Ridiculing "Reverend" and "Doctor" as "unscriptural," Alexander Campbell even employed the words of Jesus in Matthew 23:8-10 as a motto for his magazine, the Christian Baptist.
Yet church history clearly indicates that members of the Restoration Movement commonly addressed both the Campbells and Stone as "Father." Furthermore, the three founders used the term for their own clergy as well as for each other. And none of the movement’s opponents ever seemed to exploit a contradiction in the movement’s use of "Father" as a clerical title. They apparently saw no contradiction.
I don't know that that's true...Just because someone at a university says it true, I'll wait for the source material before I comment...
I guess that makes it ok then; Dad.
