Fundamentally, the practices of the Roman Catholic Church, by the Middle Ages, was
about as opposite to the practices of the Apostolic Church as you can get.
Not really, but I'll move on.
The RCC
had seized the power, wealth and glory of Rome.
Even though the emperor and the pope were quite separate people with different sovereign areas, sometimes the emperors "pulled rank" on a pope by forcing an appointment that the Vatican couldn't stop. IOW, it wasn't intended by the Church to be this way.
BTW, sometimes the same thing happened with Protestant countries as well, so why didn't you cite them on this as well?
It had largely reverted to the laws and
institutions of the Old Testament - the very things the Apostles rejected.
Not really as Jewish Law (halacha) was never imposed on the congregations, and Canon Law definitely is not halacha. All denominations and churches have laws/rules of one type or another, which is standard procedure for running any organization.
As do all religions and all Christian denominations.
alternative documents to the bible,
None surpass the Bible, and the Apocrypha was considered by many feeling that it should be part of the canon, but because of disagreements that decision was tabled until centuries later.
So?
We don't worship saints, btw.
even a 600 year reign of
terror against Jews and apostates where about one million people died.
Definitely a very sorry series of events, no doubt, but the Church never ordered nor wanted Jews, nor any other group for that matter, to be the victims of genocide. Many Catholics, including some bishops and two popes (one becoming pope later-- JPII), tried to hide and "baptize" Jews in order to save them.
I don't see the
Gospel in any of this - even Mary queen of heaven is risible.
I don't see any of the Gospel in your post-- only anti-Catholic bigotry.
BTW, Mary being the "Queen of Heaven" is not taken at the literal level within the Church as it's really more symbolic terminology because of her status being Jesus' mother. Basically, without Jesus she would be just another person.
Finally, it might be wise to look things up or even ask questions here instead of inventing or parroting falsehoods.
