What you have posted here indicates a lot of consideration on your part. Good for you.
But, with all due personal deference, my (admittedly individual, so forgive me) observation is that there are a lot of inferences to personal/individual conclusions, whether individual historical luminaries of Western Christendom or yourself.
This is one of the foundational differences in Eastern and Western Christian philosophies. In the Greek East (and originally the Latin West) there was/is dependence on conciliar thought and a rejection of doctrinal declarations of individuals who do or had/have done their thinking and made their declarations on their own. Luther, Alexander Campbell, etc...
Aside from the obvious large historical schisms (Arius, Nestorius, Monphysites), and (admittedly silly) disagreements on the calendar, the Greek East remains theologically one Church.
This can’t be said of of the West, where individual men start new movements whenever their feelings get hurt. And many of whose approaches to faith are HIGHLY legalistic.
I’m sure you and I have plenty we will agree to disagree upon.
Good day to you. Warm regards.
