T. Pierson (1837-1911) best exemplifies the integrity of the Philadelphian Church Era...
His preaching (over 13,000 sermons), extensive writings (over fifty books),
and Bible lectures made him widely known in America. He was a consulting
editor for his friend, C. I. Scofield (1843-1921), with the original
Scofield Reference Bible (1909), and was the author of the classic
biography, 'George Muller of Bristol'... A. T. Pierson's association with D.
L. Moody and his Northfield Conferences were the breeding ground for
Pierson's determination to see the world evangelized in his generation...
Arthur Pierson was himself a speaker at the Keswick Convention. This
deepening of the Christian life in Pierson saw him author one of his most
spiritually significant books, 'In Christ Jesus' (1898), where Pierson's
personal journey had led him to the conclusion that 'this brief phrase ['in
Christ Jesus'] -- a preposition followed by a proper name -- is the key to
the whole New Testament.'"
