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

Did Ignatius teach "the real presence" in the Eucharist?

This is an excellent article by Timothy Kauffman that shows that Ignatius did not teach the "real presence" (physical) of Jesus' body and blood in the Eucharist, or celebration of the Lord's Supper.

Regrettable Lutheran Arguments for the Real Presence

"On a more frivolous note- although it was meant to be taken quite seriously- Luther's supporter Johann Brenz attempted a novel refutation of Zwingli's insistence that the body of Christ is physically present at the right hand of God in heaven. Brenz computed the distance between the earth and heaven by means of his own, and arrived at the distance of 16,338,562 German miles. Given the speed of Jesus' ascent from the Mount of Olives, as Brenz estimated it, Brenz concluded that the body of Jesus could not yet have reached heaven by the sixteenth century" (Harold O.J. Brown, Heresies (Grand rapids: Baker books, 1984), 325).
