Trends come and go. Certain habits or interests rise for a time, wane, and then rise again, often at unexpected moments. One of the recent trends I have found particularly surprising and also particularly interesting is the rise (or re-rise, if you prefer) of liturgy. This may be liturgy within formal worship services of the local church or liturgy within times of private worship. Did this trend begin with Douglas McKelvey’s Every Moment Holy series? If it didn’t begin there, his books certainly popularized it. Regardless, over the past few years, we have seen a substantial number of books that share liturgies for times of worship.
