Sure, my opinion again is: any church has an absolute right to interpret the Bible howsoever it wishes, and to offer up its interpretations in market-places of ideas.
Let those which make the most sense win the most converts.
But when a church achieves worldly political power, and uses its power to have persecuted and murdered those who disagree with its interpretations, then the church becomes a weapon of evil, a tool of the devil, so to speak.
That is a burden of sin the Catholic Church will always carry.
But I also believe in forgiveness of sins, for those who honestly confess, sincerely repent and reliably promise not to repeat it.
And I'm not at all certain if the Catholic Church(s) ever quite came to grips with its terrible original sins.
What happened was a kind of civil war among Christians as well as Christians and others.
The idea of burdening the Church of Rome with a unique is a Reformation conceit. Ironical to charge Rome while overlooking the involvement of all the great reformers in politics. Zwingli died on the battle field. Luther owed his life to the Elector of Saxony and sanctioned the slaughter of the peasants who rose against against the German princes. Calvin stated his Career on the Day of the Placards, which was a religious protest, and Geneva was deeply involved in the Huguenot movement in France, which was as much political and religious. Only the small sects were innocent of the blood of other Christians, the Mennonites and the Quakers. As for a thousand years of persecution, you forget that much of the Christianizing of Europe was done by monks armed with only Bible and cross. Ireland was converted without bloodshed, and Irish monks carried the Gospel everywhere, maybe to the Americas if the story of St. Brendan can be credited.
