One of Old Pine's first pastors, George Duffield established our lively personality soon after our founding in 1768 as the Third Presbyterian Church in Philadelphia. Defying British arrest, Duffield served as chaplain to the First Continental Congress in 1774 and, with many of his parishioners, joined Washington at Valley Forge in the winter of 1776-77.

Old Pine's colonial architecture is with us today — hidden from view by facade changes made in the 1790's, 1837 and 1857. The 1768 church stands on its original foundation, retains its original brick walls (stuccoed and modified with different openings), and above it all is the original cedar shake roof (now encased in the attic below a steeper pitched metal clad roof).

The J. W. Steere and Sons Opus #344 Pipe Organ was originally built and installed in 1892 for the Unitarian Universalist Church located in Elgin, Illinois.

The historic colonial churchyard surrounding Old Pine Church retains many tombstones marking the burial location of some 3,000 late 18th and very early 19th century Philadelphians.

Someone once said of Old Pine, "If these walls could speak, what stories they would tell of courage, devotion, and of a people's love and service to God."
