As I just happen to have been reading 16th-17-century European history for the last few months …
In addition to what ** Flyer** said, there were a lot of issues. I can’t list them all here.
Much of the Catholic ritual was regarded by Protestants as idolatry. Venerating the Virgin Mary and saints, the doctrine of transubstantiation (the Catholic belief that the bread and wine literally become the body and blood of Christ).
The Roman church placed great emphasis on “good works” being required to earn a place in Heaven. Protestants believe(d) in justification by grace, that is, it’s impossible for humans to be good enough to get into Heaven (we can’t “earn” our way); men only get into Heaven by the grace of God, through faith in Jesus. To early protestants, it appeared (with good reason) that the Catholic church encouraged the belief that it was possible to buy your way into Heaven. For centuries prior, it wasn’t uncommon for wealthy men, kings, and nobles, on their deathbeds, to bequeath their lands and possessions to the Roman church, believing that doing so would balance out their otherwise reprobate lives. This is a big part of the reason the Catholic church owned so much land in Europe. And then, of course, church lands tended to be exempt from taxation. So as the Church acquired more land in every Catholic country, and because the rulers of those countries lost tax revenue from church lands, those same rulers became dependent upon The Church when they needed money …
Politics. Politics. Politics, politics, politics. For many centuries, the Pope was essentially the king of Italy (I’m greatly simplifying for brevity’s sake). And, by extension, being the king of the Church (okay, Christ is actually the King of the church and the Pope is just his representative, but tell Medieval Europe that), he wielded immense influence throughout all of Christian Europe. The Pope got to confirm kings every time there was a succession in a country. If the Pope didn’t think a king was “Catholic” enough, he would excommunicate that king, and having excommunicated the king, the citizens of that country were released from their loyalty to their king and were free (and encouraged) to overthrow him, without endangering their eternal souls. Conversely, if the excommunicated king’s subjects loved their king and supported him in opposition to the Pope, the Pope could place that country under a ban, meaning that the priests in that country would not preach, not hear confessions, and not absolve sins, thus placing all of those loyal-to-the-king citizens’ eternal souls at risk. My understanding from my reading is that this system was, more or less, extortion.
While Protestantism started as a simple desire to reform the Catholic church, to do away with the numerous abuses, the Roman Church promptly labeled the Protestants “heretics”, and from there it effectively became a separate religion, whether it wanted to be or not. It started with Martin Luthor, other Catholic clergy, and soon after the common people, it was eventually taken up by the German princes (remember, Germany at the time was not a single, united nation — it was a confederacy [more or less] of small principalities) who finally said, “Hey, waitaminnit, why is this guy in Italy telling me how to manage my business?”
From there on out, it was all politics. It was The Pope in Rome trying to be the CEO vs. the local “managers” who figured they had a better idea of how to manage their stores than some distant Pope. And don’t forget the money. These German princes were getting sick and tired of watching money flowing out of their principality and into Rome. Solution? Violence! Let’s start raiding monasteries and convents and cathedrals and taking back what is ours! Screw Rome, that’s MY money!
Anyway, I could go on and on. I’m not even going to get into Spain vs. The Netherlands (did you know that Spain used to rule The Netherlands? I just learned that.)
FULL DISCLOSURE: I am a lifelong evangelical Protestant, and everything I typed above was learned from reading The Cambridge Medieval History and The Cambridge Modern History, weighty tomes written in England by English scholars. And, of course, England is a Protestant country, as you know (thanks to Henry VIII). So I recognize that there is likely a certain bias in the writing, and of course, being a lifelong Protestant, I admit my ignorance of Catholicism beyond what I have read, and welcome clarification and correction. My above response is based entirely upon what I have read in those Cambridge volumes. To be “fair & balanced” and scholarly, once I have finished the Cambridge volumes, I fully intend to look for and study histories written by scholars from other European countries, particularly those written from a Catholic viewpoint. In particular, I would love to read a Spanish treatise on the reign of King Phillip II, and the Spanish perspective on the Armada that the English beat under Elizabeth I (hailing Nava!) as well as the Spanish POV of the conflict in The Netherlands.
That said, I had the most wonderful conversation with my pastor while we were waiting together in a stairwell immediately before my recent wedding. I mentioned that my reading of European history has given me an immensely greater appreciation for the fact that the USA’s founding father’s put in that bit about having no state-sanctioned religion. Because having a state religion is just nothing but trouble. Seriously. No sooner did a country kick the Catholics out (and sometimes, even before), Protestantism had split into different sects, and the original Protestants started calling the new Protestant sectarians “heretics”, and hey, more war. No, really. No sooner did The Netherlands kick the Spanish Catholics out than they were confronted by civil war between Calvinists and non-Calvinists. /sigh This is the entire reason I left the Republican party and became and independent voter. I just became sickened at the way my religion and my party had crawled into bed together, and were doing no good.
My pastor said “Yeah, that’s the problem with the fact that most people haven’t studied history. It just keeps happening.”
