Christian recently asked a question regarding liturgical theology to which I provided an answer. However, in doing so, I realized my knowledge of "recent work" in the topic is 30 years old. For example, my knowledge of Protestant liturgical theology is frozen in the Gail Ramshaw - Paul F. Bradshaw era. I have seen a bit of new material on reformation worship (Jonathan Gibson, Mark Earngey) but otherwise I'm terribly dated on the Protestant front. Can you identify some theologians or worship scholars that I should know?
