Jordan is an interesting thinker and theologian. He has a unique, very insightful way of reading the Bible. He understands the Bible's symbolism in ways that most teachers miss, or at least don't articulate. I suppose some of his readings are fanciful, and I don't agree with everything. But more often than not, I am edified by his work.
The Sociology of the Church is a great work on ecclesiology--that is, what the church ought to do, and how it ought to be done. He is rigorously biblical, and unafraid of embracing unpopular practices, not to be a contrarian, but out of a desire to be faithful to Scripture.
The book is a series of essays, and he covers a lot of ground in the book. It is a work similar to his book "The Reconstruction of the Church" which is a collection of essays by Jordan and other writers.
In this book, Jordan covers things such as liturgy, worship music, preaching, communion, church architecture, church government, church and state interactions, a pastor's attire, the sacraments, revivalism, conversion, healing, the Sabbath, catholicity, denominationalism, the para-church, and others I'm sure I've missed.
I really enjoyed this and recommend it as a good work on strengthening the church and becoming a more faithful witness to our unbelieving world.
