As stated on this page here, catholic.com/tracts/the-real-presence, St Ignatius of Antioch said that the Host was the real body of Jesus. Here is the exact text:
*“Take note of those who hold heterodox opinions on the grace of Jesus Christ which has come to us, and see how contrary their opinions are to the mind of God. . . . They abstain from the Eucharist and from prayer because they do not confess that the Eucharist is the flesh of our Savior Jesus Christ, flesh which suffered for our sins and which that Father, in his goodness, raised up again. They who deny the gift of God are perishing in their disputes” (Letter to the Smyrnaeans 6:2–7:1 [A.D. 110]). *
Seeing how St Ignatius was a student of John the Apostle, this would seem to make a very good case that the Host is Jesus real body (seeing how we could hardly argue with a source so close to the Apostle John, who had the truth). The Letter to the Smyrnaeans is considered an authentic letter according to St Ignatius’ wiki page (en.wikipedia.org/wiki/Ignatius_of_Antioch). However, some of his letters have been altered for the purpose of retrospectively inserting arguments for the catholic church to fight against heretical churches that were springing up after Ignatius had died.
What i want to know is, is the letter to the Smyrnaeans water-tight (in so far as the remark to the Host) or do protestants contest the authenticity of this letter so as to argue against the real presence in the host? Anyone ever hear it contested or do protestants accept its authenticity but just ignore it?
