Now just a moment, my FRiend. You were the one pointing out that ekklasia is a public meeting, not associated with a specific gathering of believers. I simply pointed out that this is true and Rome has absconded with this meaning and replaced it with "CHURCH" so that it can make an institution out of thin air. There is nothing "Protestant" or biased in a normal hermeneutic which simply extracts a text's ordinary meaning.
It is you who is wringing an organizational mandate out of nothing here. No reasonable reader could conclude that the word "ekklasia" means anything more than a normally called public meeting. You said it yourself. Now, you wish to twist that observation into a "bias". Sadly, Rome must require such obedience because so much is at stake.
I was very specific in pointing our that the term "ekklesia" within the Greek culture and language was associated with a very formal institution, not a loose grouping of like minded persons. I cannot see it how the original meanings can or should be changed to suit a particular doctrine, theology or tradition.
If you want to go even deeper, there is considerable evidence that the concept of a Hebrew Qahal was associated with the term within the Gospels. The more you dig, the more you find the Traditions of the Church to be in sync with the Apostles.
Peace be with you.
