I know the writings of Ignatius, Justin Martyr, Irenaeus, Augustine and so on really prove that the Catholic Faith was around since the Apostolic times, but are there other writers who’s writings go against Catholic teachings? **Are there ancient writers who’s writings speak against the Real Presence in the Eucharist? **Are the writings we accept as the “Church Fathers” approved by the Holy See and that is why we accept them or are they the ONLY writings available from the time? If they are the only writings we have then it seems to prove that we are the ONLY church which can trace itself back that far, but if there are others then maybe I’ve only heard one side of the story. I know there’s writings like Gospel of Thomas and Gnostic writings, but I’m looking for Church leaders or theologens that were accepted but were later squelched by the truth of the Catholic church.
