What? That controversy was about the mode of the presence of the Body and Blood of the Lord in the Eucharist. There were several major controversies about that. There was hyper-realism, there was hypo-realism, there was moderate realism (which is the Catholic position). But there was never any claim that the Mass was something other than what Jesus did at the Last Supper, and commanded the apostles to do “in memory of me.”
In other words, your response is no response.
You still have not explained the total absence of controversy, for 1500 years, about the veneration of saints, the Mass, and all the other popish “inventions” you listed.
All of a sudden, in the Fourth Century, the Christian religion was maimed and twisted by idolatry and superstition, and NOBODY NOTICED and NOBODY MINDED.
Easy. Catholicism eradicated them as *heretics*.
It's not hard to have no controversy when all your opponents are either dead or threatened with death in the most gruesome ways.
