Most Roman Catholics, and virtually all Bible-believing Protestants believe in the concept of original sin. Reformers clarify with the further concept of total depravity. I went no further than this concept. If you believe that all men are born "basically good", then I will just have to wish you the best of luck with that. When I look at the real world I don't see that at all. Your side relies on man's inner goodness, and we rely on God. Paul teaches total depravity clearly, which I surmise is a great reason why Apostolics don't like Paul.
The Orthodox believe in the original sin. The East never taught the Augustinian teaching of total depravity and innate "guilt" as a consequence of that sin or, for that matter, that unbaptized babies go to hell. [unfortunately, Blessed Augustine never completely shook his Menachean beliefs]

Man is born innocent, not good. There is a difference. The consequence of the original sin is like drug addiction passed on from the mother to a child. The child will crave the drug but that craving is none of his doing. He bears no guilt or responsibility for that sin.
And, just as a drug-addicted infant is not dead and can be cured by a physician, so can we be cured of our fallen state with God's help, provided we ask for His help, and cling on to Him.
When I look at the real world I don't see that at all
Although many say "Lord, Lord" most don't follow in His footsteps. They preach His words but they don't do live by them. Faith is life. It's how we live that we show our faith. Unfortunately, in the Protestant world, it's okay to live a carnal life and cling on to faith, as Luther reminded us with his example.
Your side relies on man's inner goodness, and we rely on God
Your sides relies on private interpretation of God. Our side relies on God's mysteries (sacraments) of His Church. If we believed man was essentially good, the Apostolic Church would have no reason to exist. The Church exists for sinners, not saints.
It is precisely because we believe that continue to sin that we seek help and forgiveness in our struggle against repeating the same sins.
If I believed I did nothing bad, and had nothing to confess, why should I ask for forgiveness? It is your side that considers all believers as "saints." It is your side that thinks once he accepts Christs man is good!
Paul teaches total depravity clearly, which I surmise is a great reason why Apostolics don't like Paul.
I got news for you: the Church loves Paul; I don't. The Church is Pauline, not Petrine. I find that unfortunate but that's how it is. The Orthodox liturgical readings consist of Pauline Epistles and the Gospels. That pretty much says it all. Yet we do not teach Paul, but Christ. We do not stand (if there are pews) when Paul's letters are read. We stand only when the Gospels are read.
We interpret Paul in the light of the Gospels, not the other way around. When Paul says "God [sic] raised Christ", the Church says "Christ rose." If Paul says Christ is an "image of God" the Church says "Christ is God." With Protestants, Paul and Christ are one and the same thing. We don't worship Paul. Your side does.
