I think you need to do more than scratch the surface and see what is really there. It is not just an essay on docetism, it is far deeper than that.
Here is not the place for a long dissertation, but let me give you one example of food for thought. One single word of many examples clearly contests your interpretation.
" valid" a valid Eucharist can only be performed by a bishop - says a man taught by an apostle. So clearly that is the true faith, passed by paradosis - handing down - tradition,
A symbolic or memorial Eucharist can have no concept of validity or efficacy.
The only context in which the word valid makes sense - is in the context of a sacrament.
Which dovetails with scripture - How indeed can you eat and drink judgement on yourself if the Eucharist is only symbolic? Justin Martyr calls it " flesh. Our Lord used the word " gnaw" not consume which horrified his audience at capernau,. And in smyrneans 7:1 " they confess not the Eucharist etc...
Nothing you have said, alters an iota my general point.
The early fathers demonstrate a liturgical, sacramental church that believed in real presence, valid only if performed by clergy in succession.
None of the post reformation offshoots can live up to that.
The Catholic Church is not an alternative splinter, it is the very root and trunk of a tree, traceable back to the acorn. A few branches dropped off at the reformation.
Sadly because of logically provable falsehoods like " sola scriptura"
I have read many of the works of the Church fathers. 16 years of Catholic education saw to that. I even read them within context of what they were actually arguing against. Unlike plucked out of context eisegesis quotes used by apologists.
All of it. I actually read what comes before and after what Catholic apologists take out of context reading in their medieval metaphysics.
Unfortunately Ignatius was not giving a dissertation on the real presence but refuting Docetism.
I would say the Holy Spirit Inspired Holy Scriptures. Which come before the early fathers.
