I don’t have time at the moment to go point by point, but the difference between the interpretations and theological approaches between East and West are more matters of terminology and approach.
The difference with Protestants is they throw the baby out with the bathwater, and they can’t even agree among themselves about matters of fundamental Christian dogma.
That is not true in the least.
THIS is what's foundational in our Christian faith, no matter whether we believe in election or free will. THIS is the unifying *dogma* (if you will)......
Ephesians 2:1-10 1 And you were dead in the trespasses and sins 2 in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience— 3among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind.
4But God, being rich in mercy, because of the great love with which he loved us, 5even when we were dead in our trespasses, made us alive together with Christ— by grace you have been saved— 6and raised us up with him and seated us with him in the heavenly places in Christ Jesus, 7so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus.
8For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, 9 not a result of works, so that no one may boast. 10For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.
Romans 10:5-13 5For Moses writes about the righteousness that is based on the law, that the person who does the commandments shall live by them. 6But the righteousness based on faith says, "Do not say in your heart, 'Who will ascend into heaven?'" (that is, to bring Christ down) 7or "'Who will descend into the abyss?'" (that is, to bring Christ up from the dead).
8But what does it say? "The word is near you, in your mouth and in your heart" (that is, the word of faith that we proclaim); 9because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. 10For with the heart one believes and is justified, and with the mouth one confesses and is saved. 11For the Scripture says, "Everyone who believes in him will not be put to shame."
12 For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him. 13For "everyone who calls on the name of the Lord will be saved."
I'm not asking you to explain why there are differences between you two, only that there are differences and some of those are so serious that reunification has not happened for over a thousand years. To insist that because "Protestants" - and I put that word in quotes because for most of you anyone who isn't Catholic falls into that bucket - have differences in "theological approaches" and "interpretations" means none can be correct about anything is overly dramatic.
While there are many groups that call themselves Christian, not everyone that says "Lord, Lord" shall be saved. There certainly are central tenets of the Christian faith that are enumerated in Scripture and, of course, in traditional beliefs that it would not be difficult at all to separate true believers from false ones. One of the major reasons why so many of us here stress the place of the Bible in knowing truth from fallacy is because the Scriptures are infallible and inerrant coming from God himself. Jesus fought Satan's temptations by repeatedly saying, "It is written", I believe that we were told about that exchange for just that very reason.
