It is natural because our worldview affects how we reason. Also it marks what is important to us and what questions we ask. Theology addresses our questions.
There is no way, IMO, that Calvinism would have been born were Calvin trained as a theologian rather than a lawyer.
That does not make it wrong, but it addresses justice by addressing issues unique to that period in Western history.
The "reformers" substituted their own thinking of God's word, they came up with a whole new interpretation of things.
Sort of
like the Baptist folks who themselves departed from what the "reformers" came up with, now having their own interpretation.
Haaaaaaaa! That's funny. We have been through all this stuff before haven't we? You folks have departed from what was taught to the faithful from the beginning. Come on, you should know that by now.
But to answer the OP. The Eastern Orthodox Church is the other lung to the Western Orthodox Church more commonly known as the Roman Catholic Church, or the Latin Rite of Christianity. I view it favorably, as it holds to the highest order of orthodox Christian teachings. They have not strayed from the truth (as other Christian denominations have done) that came directly from Jesus Christ, God incarnated upon this earth
"The true Christian Church did not come about until the 17th century, brought to the world by the great John Smythe"
(From Chapter 5 , Paragraph 6 of the book "Fables and Other Ridiculous Stuff").
I chose a different route, yet cannot claim to have studied it in-depth.
I’ve really only gotten an overview, but quite a bit was firsthand.
Made for an intriguing experience, what I would call fun. :)
