A friend of mine shared this quote with me, and I think it is most poignant for churches today.
J.H. Thornwell, the great Southern Presbyterian theologian of the nineteenth century, noticed the churches in his day moving in a dangerous direction, a direction that he feared might compromise the very message of the church. In a letter written in July 1846, Thornwell warned:
Our whole system of operations gives an undue influence to money. Where money is the great want, numbers must be sought; and where an ambition for numbers prevails, doctrinal purity must be sacrificed. The root of evil is in the secular spirit of all our ecclesiastical institutions. What we want is a spiritual body; a Church whose power lies in the truth, and in the presence of the Holy Ghost. To unsecularize the church should be the unceasing aim of all who are anxious that the ways of Zion should flourish.
(This quote is from a book about Jonathan Edwards, A God Entranced Vision of all Things.)
