Hearsay or personal opinion =/= God's word.
Most of what passes for "oral transmission," allegedly handed down from the Apostles, isn't that at all, but is simply folklore or someone's theory that was later pronounced authoritative by the institutional church. Examples include the Assumption (of Mary) and Transubstantiation.
Actually, transubstantiation is a completely valid interpretation of the New Testament pericopes which deal with the Eucharist. I would further argue that it is more valid than Zwinglianism and Memorialism.
The reason for this is simple, as Martin Luther famously carved into the table (or wrote on it with chalk) at the Marburg Colloquy,
HOC EST CORPUS MEUM
To wit, our Lord did not say “This is a symbol of my body” or “This is a memorial of my body” but rather “This is my body.”
This has the effect of excluding all Eucharistic interpretations outside of what I think we might call the Calvinist-Eastern Church scale, where the Calvinist end represents a real spiritual presence in the consecrated elements, and the Eastern Church end represents a real change equal to or exceeding transubstantiation, with the Lutheran doctrine of the real presence “in, with and under” and the Roman Catholic doctrine of transubstantiation in the middle (I put the Eastern churches on the extreme simply because their Eucharistic theology, although sometimes described by a minority of Eastern Orthodox theologians as transubstantiation, does not, according to the majority of Eastern Orthodox, Oriental Orthodox and Assyrian commentators depend on Aristotelian categories; specifically, there is no dichotomy between substance and accidents).
Now, regarding the Assumption of the Blessed Virgin Mary, or the Dormition as it is known in the Eastern Orthodox Church (Oriental Orthodox Christians interestingly tend to call it the Assumption, but the meaning is the same), while this doctrine is not defined within sacred scripture, there are no opposing Patristic narratives, and what is particularly striking is that there are no relics of the body of the Blessed Virgin Mary, whereas we have relics of just about everyone else, even the head of St. John the Baptist. Given the huge emphasis the early church put on the relics of apostles, martyrs and evangelists, to the extent that the early church celebrated its services in the cemeteries and catacombs, with Vespers at Sunset, Matins and the Eucharist at midnight, and Lauds before dawn, a pattern still observed in monasteries, and given that the monuments marking the graves of martyrs and other saints were used as altars on which the Eucharist was consecrated, a practice which continues with the placement of relics in the Holy Table and in
antimensia in traditional churches, it strains credulity to suggest that the Mother of God died an ordinary death and was buried - especially when we consider that she was physically closer to God than anyone else, and for long periods of time, by virtue of her status as His mother.
By the way
@MarkRohfrietsch , you did that special beautiful service on August the 15th of last year, right?
Also, reverting to Lutheranism, one thing I really admire about Martin Luther is that he did not attend the Marburg Colloquy with a view towards compromising or working out some sort of pan-Protestant ecumenical solution, but rather, he went there with the mindset of a confessor of the faith. The man had a lot of courage. I would venerate him as a saint had it not been for the tragic lapse in judgement he made late in life concerning Judaism and his anti-Semitic collaboration with Lucas Cranach the Elder. If it could be shown, however, that he was suffering from dementia, I would be prepared to change my mind on that point, because, ceteris paribus, Luther is really someone who I want to venerate.
As it stands, I disregard the Three Chapters of Justinian and consider Origen and Theodore of Mopsuestia saints worthy of veneration (and at least in the second case, I am not alone; the Church of the East venerates him as Mar Theodore the Interpreter).
