I agree with some of what you two have said, but I have to point out that you're very wrong about Orthodoxy. You seem to just be randomly lumping it in with Roman Catholocism without having actually done any real research into Orthodoxy's history or listened to any Orthodox explanations of the religion and its origins. In short, Orthodoxy is the only true Christianity.
Jesus started the church, and left the Holy Spirit to guide them. He made it clear that there is much more to learn beyond what he has said during his ministry, and that this knowledge would be gained through the Holy Spirit. The Holy Spirit was given to the disciples, and they went on to spread the Christian church, following the practices of worship that Jesus laid out for them. They started five Patriarchates, each in a separate city: Antioch, Rome, Jerusalem, Constantinople, and Alexandria. For centuries, they passed down the traditions of the church from the first disciples. When they had disagreements, they got together in Ecumenical Councils to resolve them. Only when the council agreed unanimously did they settle on a decision. Through this council, the Holy Spirit worked to ensure that they didn't stray from the path.
In the year 451, the European side of the church lost contact with the Oriental church in Asia. This was the first great split of Christianity, though it wasn't due to disagreement but due to a loss of contact. In the meantime, they each decided the other must have become heretical and that they were the true church.
By the year 1054, the European church had remained unchanged from the religion that Jesus passed down. But now the Patriarch of Rome decided that he was more important than the others. The Great Schism occured, and the Roman Catholic church was born. Without the Ecumenical Council, Rome could not be guided by the Holy Spirit, and so it gradually changed its doctrine. It decided that its Patriarch is now a "Pope" who is the representative of Christ on Earth, and many other things that have no basis in the Bible. Meanwhile, the church of Eastern Europe and the Middle East stayed on the true path, and became known as the Eastern Orthodox Church.
Eventually, when the printing press was invented, the masses got their hands on the Bible, and they realized that what the Roman Catholics were doing didn't match the Bible, and so the Protestant Reformation happened. Protestants discarded all tradition, even the traditions that went back to the early church. Not for any good reason though, it was really just a flip-the-table move much like Communism's "solution" to the excesses of Capitalism. It exploded into thousands of different churches/denominations because when all you have to go on is the Bible, there's not much you can do to prove that your interpretation is the right one (which, consequently, is why tradition is important). They didn't realize that when Jesus denounced tradition in the Bible, he was denouncing the tradition of Man, but else where in the Bible he explains the importance of maintaining the tradition of God, and the purpose of the church is to do exactly that. The basic contradiction of Protestantism is that they believe the Bible is the word of God, but the Bible was compiled by the early church around the 4th century. This means that the only way you can believe the Bible is the true and complete word of God would be to believe that the Holy Spirit was guiding the early church. In which case, since the Orthodox Church of today is still the same as the early church, then Protestants have no argument on which to claim that Orthodoxy is not the true faith, because if they deny it then they deny the only thing that gives validity to their own Bible.
In 1990, the Eastern Orthodox Church finally made official contact again with the Oriental Orthodox Church that had split away back in 451. They wanted to resolve their differences, so they sat down to carefully compare their doctrinal beliefs. After careful examination and review, they realized to their surprise that although some of the terminology they used was different, their interpretations of the Bible and the practices of their church were still 100% the same as each other, despite being separated for 1500 years and despite them both having had numerous Ecumenical Council decisions since then. And so, the two churches rejoined one another as the Orthodox Church, as indeed they had never truly separated in spirit. This is because the Holy Spirit was guiding them both. Now compare that to the gradual doctrinal shift of the Roman Catholic church ever since 1054, or the constant changes of the Protestant world even within denominations.
Jesus Christ said that he would set up his church (singular), and that the forces of hell would not prevail against it. So far, he's been right, and that church is the Orthodox Church.
