Very interesting article on the real presence in the Eucharist in the early church

"This article will examine the writings of Clement of Alexandria, Tertullian of Carthage, Irenaeus of Lyons, Justin Martyr, Ignatius, and a contribution from Origen in order to show that the ancient church never believed, taught or even conceived any doctrine like the real presence dogma."  Brian Culliton, at his "onefold" wordpress blog
