Look what I just found online: The History of the Doctrine of the Holy Eucharist by Oxford scholar Darwell Stone. This is bar none the best historical overview I have ever read on the theology of the Eucharist. In this two part tome, Stone traces the church’s beliefs about the Eucharist from New Testament times through the late nineteenth century. The book is arranged chronologically with copious quotations from the various theologians.
Both editions free and full online.
