There is no unanimity in church history on this issue which the Roman State Church can rest upon and which you are desperately trying to argue from.
What falsity! Basic facts:
You can't produce a single example of a formal rejection of this doctrine which was clearly taught by Mark,John, Matthew, Ignatius, Irenaeus, Cyril, Augustine,Athanasius Chyrstostom, etc--along with the other Catholic Biblical mysteries such as 1 Tim 4:14 and Heb 6:2--so you just assert the opposite, even though there is nobody that generally believeed what you do Church history before 1100 A.D, as you tacitly admit.
Cf.Mt 5:14, which says that we, the Church, cannot be hid.
You also seem to say that the Church at some points did not have unanimity, as though the Lord's prayer for unity was answered, even in His Own Body,which is the fulness of God the Son. Cf. Eph 1:23, Jn 17:11. This is contrary to faith.
You also say that Irenaeus did not believe in Transubstantiation , even though Irenaeus was much clearer than Clement of Alex., which gave you a weak excuse to evade Scripture. But even Clement said:
And the one, the mixture of wine and water, nourishes to faith; while the other, the Spirit, conducts to immortality. And the mixture of both--of the water and of the Word--is called Eucharist, renowned and glorious grace; and they who by faith partake of it are sanctified both in body and soul."
Clement of Alexandria,The Instructor,2(ante A.D. 202),in ANF,II:242
And Irenaeus is explicit:
"If the Lord were from other than the Father, how could he rightly take bread, which is of the same creation as our own, and confess it to be his body and affirm that the mixture in the cup is his blood?" (Against Heresies 4:33–32 [A.D. 189]).
"He has declared the cup, a part of creation, to be his own blood, from which he causes our blood to flow; and the bread, a part of creation, he has established as his own body, from which he gives increase unto our bodies. When, therefore, the mixed cup [wine and water] and the baked bread receives the Word of God and becomes the Eucharist, the body of Christ, and from these the substance of our flesh is increased and supported, how can they say that the flesh is not capable of receiving the gift of God, which is eternal life—flesh which is nourished by the body and blood of the Lord, and is in fact a member of him?"(ibid., 5:2).
What more do you want? Where is your faith?
This is a good example of how some "reformed" traditions habitually don't see what the Scriptures or basic Church historical facts indicate: namely that the Church always believed in the Truth--though I fully endorse the idea of doctrinal and Regal development (Cf. Luke 2:52, Mr 4:31-32)--as to Communion and Apostolic Succession through this on Communion.
If men look for too much precision in history--as though men weren't men; or as though the Catholic Church calls the fathers "infallible at all times"--and, to add to the error, do not take the Word at his plain, (albeit entirely Mysterious), words (Cf. Jn 6:51-57etc, Mk 14:22, Mt 26:26)....then where is their relationship to the Holy Ghost?
Here is Athanasius, who--like the other fathers I mentioned--taught an honest and interpretation of Scripture, and was a true believer in the Trinity:
"You will see the Levites bringing the loaves and a cup of wine, and placing them on the table. So long as the prayers and invocations have not yet been made,it is mere bread and a mere cup. But when the great and wonderous prayers have been recited, then the bread becomes the body and the cup the blood of our Lord Jesus Christ....When the great prayers and holy supplications are sent up, the Word descends on the bread and the cup, and it becomes His body."
Athanasius,Sermon to the Newly Baptized,PG 26,1325(ante A.D. 373),in ECD,442http://www.cin.org/users/jgallegos/trans.htm
Lastly, why do you call people who follow the Trinity alone "spiders"?
