Takeaway: Expressive Worship and Formative Worship, while both valid, have different purposes.
It is good to re-read books. I can not remember where I read it, but I remember a discussion about the difference in reading habits of people a couple hundred years ago. The short version is that books used to be very expensive. So you would read and re-read a book several times because you only had a few options of what books to read.
Today books are cheap. I routinely pick up books for a couple dollars or even free. So we tend to read a book once and move on to the next idea. I have put a goal on myself to re-read at least one book a month. I rarely re-read books quite that often, but almost every time I re-read a book I am reminded about the importance of re-reading. Maybe others are more careful readers than I am. But I almost always find significant ideas that I either missed on the first reading or I have forgotten.
The most important idea from You are What You Love that I missed on the first reading is the clear understanding of the difference between what Smith calls Expressive and Formative worship. For Smith, expressive worship, the predominate focus of modern evangelicals, is about the importance of bringing praise to God. Smith does not say it is wrong to expressively worship. But he is not sure that expressive worship should be our primary focus and this is for several reasons. 1) Expressive worship is focused on what we do for God instead of what God has done. 2) Because of our age of authenticity, the temptation for expressive worship is to always seek out the new and innovative because repeated expressive worship feels less authentic. 3) Because of point one, the only real place for the congregation to participate in expressive worship is the music portion of worship. So expressive worship ends up minimizing the full range of worship in a service.
Instead Smith believes that we should approach worship as primarily formative. Formative worship is focused on what the activity of worship does to us. Music reminds us of themes of worship, creeds reminds us of the historical and catholic character of Christianity, the eucharist reminds us of the sacrifice of Christ and the power of the Spirit to act in us on a daily basis, the word reminds us of the message of the gospel.
I think that I have been so shaped in my evangelical formation on the importance of expressive worship that I have missed Smith’s distinction between expressive and formative worship in the first reading.
The main focus of the book is that we are shaped by habits that occur in the pre-cognitive portion of our brain. Things that we do without really thinking of them. So we should strive after creating habits that help us move in the direction that we want to go as Christians.
