The Auburn Affirmation was a document dated May 1924, with the title "AN AFFIRMATION designed to safeguard the unity and liberty of the Presbyterian Church in the United States of America", authored by an eleven-member Conference Committee and signed by 1274 ministers of the PCUSA. The Affirmation challenged the right of the highest court of the church, the General Assembly, to impose the five fundamentals as a test of orthodoxy without the concurrence of a vote from the regional courts, the presbyteries.
In1910, 1916, and again in 1923, the General Assembly declared that every candidate seeking to be ordained in the Presbyterian Church ought to be able to affirm
The Auburn Theological Seminary history professor, Robert Hastings Nichols, proposed to challenge this procedure of repeatedly affirming additional standards of orthodoxy, besides the Bible and the Westminster Confession of Faith - which were the only standards of orthodoxy officially recognized by the church. The Affirmation denounces that procedure of affirming the Fundamentals in the General Assembly, as a contradiction of the history and polity of the Presbyterian Church. It was drafted and signed by a writing group, but primarily Nichols and Henry Sloane Coffin, with the intention of presenting it to the General Assembly of 1923. Coffin suggested that the Affirmation should be signed by ministers before being formally made public; and in accord with that advice it was circulated for signature in preparation for the General Assembly of 1924. Although the Affirmation did not officially come from Auburn Theological Seminary (at that time located in Auburn, New York), the name "Auburn Affirmation" has been attached to the document from the beginning, because of Nichols' influence as the originator of the idea.
The Auburn Affirmation was the culmination of the Fundamentalist-Modernist controversy, which by 1924 had been a conflict of more than thirty years within the Presbyterian Church (USA). It is generally regarded as signalling a turning point in the history of American Presbyterianism, because it garnered the support of both theological traditionalists and liberals. Besides the 1274 signatories, the document as submitted claimed the support of "hundreds of ministers who agree with and approve of the Affirmation, though they have refrained from signing it."
Referring to the five fundamentalsasparticular theories, the Affirmation's argument is succinctly summarized in two sentences:
