Why Do Presbyterians Observe Holy Days?

Dr. Samuel Miller, Professor of Ecclesiastical History and Church Government at Princeton Seminary wrote confidently in 1835 'Presbyterians do not observe Holy Days.'1 Yet some 164 years after the book in which Miller made that bold declaration was published, an informal survey of 30 churches in the Presbyterian Church in America, the largest of the theologically conservative Presbyterian bodies in the United States, indicated that 83% of the churches do regularly celebrate Holy Days.

What happened in those intervening 164 years? Did the practice of Presbyterians change significantly in that time or was Miller's declaration inaccurate when he made it? What might have brought about such a radical change if it did in fact occur? This essay will seek to answer these questions.
