The RCC does not believe in Sola Scriptura, which is the very hallmark of the Christian faith.
Incorrect.
The Catholic Church does not limit itself to the Bible as the Early Christian Church did not even yet have the New Testament. They gave mind to the Old Testament and to the Oral words spoken by the Apostles. They followed the traditions of Jesus' earliest followers, the Apostles. To this day, the Catholic Church continues to follow Apostolic tradition, and of course, scripture.
The RCC bases salvation by works alone
Not just wrong, but totally wrong.
Redemption and salvation are given to us by grace from God. We receive the grace of salvation salvation through the grace of faith and then faith working itself out through love/acts of love. This is taught in Galatians; James also taught this, so an early teaching taught and practiced by the Early Church and practiced by the Catholic Church down through the ages.
the RCC is guilty of atrocities including the inquisitions
Protestant churches are also guilty of atrocities--all human groups and organizations are. The sad part about so much of this is that most of these things they start out with not only good intentions, but the best of intentions. Actually study the Inquisitions. In a time Church and State worked together, it was the Church who came to the aid of those being unfairly punished by the State. Anyone the State labeled guilty had the right to appeal to the Church who could overturn the prior decision. With this custom in place,
No one expects the Spanish Inquisition. This Inquisitor (forgotten his name, look it up) is responsible for the horrendous number of deaths, and even at the time was censored by Rome. However, the State was on the side of the Inquisitor, but to this day it is that person, actually acting for the Spanish government at that time, who is the cause of the Catholic Church being blamed for the Inquisitions gone wrong. Could the Church have done more? Sure. The Church instead of merely calling the man in for censure could have excommunicated him. When wrong is occurring, something can always be done.
RCC is also known as the "Great Whore of Babylon"
Wrong.
Don't you people ever do any actual Bible Study using scholarly sources? I know some do, because one of the best scholarly sources on the Book of Revelation was written by a non-Catholic.
The Douay Bible contains books (Apocrypha) that were not inspired by G-d.
Absolutely. The Catholic Church retained books used in the time of Christ and the Early Christians. A few hundred years later, Judaism put together their own Canon, and chose not to include these books. About a thousand years after that, Protestants said, Hey, let's only follow the books the Jews who lived over a hundred years after Christ decided to follow, and toss out the others in use at the time of Christ.
I do believe the RCC and the Jesuits were instrumental in the Holocaust.
Of course you do, that doesn't surprise me at all. As in all your other objections, these beliefs are/have been based on pure emotion, not on study of primary sources. You have no interest in what the Church was doing as a unit. You are going after individual and subsets who happen to be Catholic. It's not as if it no one knows that that Adolf Hitler was baptized Catholic and raised in the Catholic faith. The fact that he rejected Catholicism is often overlooked.
And contrary to Vatican II, anyone who is not Catholic is still branded an heretic.
Read that again. You finally admit that the Catholic Church does not look upon other Christian denominations as heretics. Once more, pure emotions drives you to your conclusion that you are branded as a heretic. This is wrong on so many levels. It is impossible to brand anyone who is not a practicing Catholic a heretic. That would be like accusing a citizen of another country treason against the United States. One has to be a citizen of the US before one can be accused of treason against his own country.
In the same way, a practicing Catholic can be accused of heresy, but not anyone else. The best you can do is complain that the Catholic Church won't even regard you as a heretic!
