Our History

The Library is named for Philip Schaff, Professor of Church History and Biblical Literature (1844-1865)

"Philip Schaff has been described as a mediating theologian who was able to bring reconciliation and cooperation across many sources of division.

Perhaps that is his greatest and most important legacy for today's Christians. We must work together - we simply don't have the leisure in our post-modern, post-Christian society to indulge in some of the battles that have plagued American Christianity in the past.

Schaff would never accept an apathetic, indifferent, theologically vapid unity, but he would insist on working together, despite deeply held differences, in the proclamation of the Gospel and the work of the Kingdom."

-- Stephen R. Graham, "The Protestant Principle and the Catholic Substance," New Mercersburg Review No. XXVII 100-101
