Jesus said “ This is My Body”....and He said “It’s finished”...and He sat down at the right hand of God. A priest never sat down without finsishing the task. He gave His body...it’s a done deal.
As for Igantius and any others you might quote....we don’t follow authors of by gone years...we are to follow Christ. What they might say and what Christ says are often in dispute which is why they will never all be in agreement.
So yes, if they took this “consuming Christ” as their own then yes they errored greatly...blasphemous...well sure.
You’re forgetting these are men and too many put too much into what they say. Their writings are an aid...not scripture.
“what they say and what Christ says are often in dispute”
St Ignatius believed Christ when He said “This is My Body”
Of course, he had an advantage on you, he was personally taught the Catholic faith by St John, who penned the 6th Chapter of the Gospel of John. He could personally ask, “John, what are we receiving when we eat the Eucharist”? I would think the Word of God would be sufficient for you, “sola scriptura” remember?
But seeing as it is not, you would think the unanimous teaching of the Church for 1,500 years might sway you, not just St Ignatius or St Justin, but everywhere the Apostles spread the Gospel in the known world, there you would find the One, Holy, Catholic and Apostolic Church.
So, St Ignatius is in heaven saying how much longer until they are avenged and you sit in your comfortable house calling him a blasphemer.......says a lot!!
