The goal of the Reformation can be summed up in one brilliant quote from William Tyndale: "I defy the Pope and all his laws. If God spareth my life ere many years, I shall cause the boy who driveth the plough to know more of the scriptures than thou doth."
This was spoken to a Catholic bishop during a very different era. Christians didn't just have Bibles sitting on their shelves gathering dust (hint hint). No, the scriptures were kept under lock and key by the Catholic Church. If you wanted to know what they said, you required permission to read them, and you weren't allowed to interpret them contrary to the teachings of the Catholic Church. Furthermore, they were very difficult to get in English. Translating the Bible was actually a crime punishable by death, which Tyndale himself eventually did suffer.
In the modern day, the Catholic Church lacks this power. They are no longer in a position to kill those they consider heretics. Thus, they have resorted to far more peaceful means of manipulation. Modern Catholics are allowed to own, and even study the Bible, but they are still forbidden to interpret it differently than "holy Mother Church" interprets it. What that means is if the Bible says "yes", but the Catholic Church says "no", a good Catholic will claim the Bible says "no". If the Bible says "no", but the Catholic Church says "yes", a good Catholic will say the Bible says "yes".
We see this all the time. The Bible often finds itself in conflict with Catholic doctrine. The papacy, purgatory, the Marian dogmas, these are just three examples of Catholic doctrines the Bible opposes. But Catholics, assuming the authority of their Church, insist that these things are true, and even twist the scriptures to prove them. They famously twist Matthew 16:18 to support the papacy. They twist 1 Corinthians 3:15 to support Purgatory. They twist Luke 1:48 to support their undying devotion to Mary. The Catholic power to violently enforce their eisegesis is dead, but the eisegesis itself is not.
The beauty of the Reformation is that, with the violence out of the way, and the ease of access to the scriptures, we are free to exegete the scriptures both independently and as a group. We do not have to say "yes" when the Bible says "no", or "no" when the Bible says "yes". We do not have to inherit the errors of our leaders. We are even called, by these self same scriptures, to test them. And that is a very good thing, because even the best of the best had their errors.
Case in point, take John Calvin. Calvin's fame as a Reformer is probably matched only by Martin Luther (who had his own set of problems), and his views on predestination are held by a lot of Christians today. This is not even without merit, as with the exception of Limited Atonement, there are scriptures that at the very least seem to support Calvinism. However, I find Calvinists can often be quite Catholic in their support of these doctrines. They frequently appeal to history as if that overrules scripture, and when scriptures are brought up that seem contrary to Calvinism, they reinterpret them using the same flimsy logic Catholics do.
Now, since this article was not intended to bash Calvinists, that is the extent of what I plan to say here about Calvinism. What I will say is that we should embrace the freedom we have thanks to the Reformation. We are now free to study the scriptures, and according to those scriptures, this makes even the simple man wise. When we delight in them. When we make a point about studying God's word, listening to Him above all other authorities, our wisdom inevitably increases. But when we make a point about listening to other authorities regardless of what scripture says, we add our leaders' errors on top of our own. Let your flaws be your own, and let God be the flawless one who corrects us.
