jokus-Oh boy. First, why are you speaking for someone else?
That doesn't stop some Protestants from making a "canon within a canon" by placing Romans and Galatians above and beyond what Jesus says in the Gospels so as to maintain the false idea of salvation by faith alone. As a result, verses that are from "outside" this "higher canon" get little press.
In order to reduce my error rate might I suggest you refer to Calvin's Institutes or his commentaries. While I don't agree with everything he has to say I find him to be a little more easier to read than some of the early church fathers.
I am not interested in a dead heretic's thoughts, but a live Christian's opinion. There are many more worthy things to attend to then Calvin's false presumptions. As you admit, you don't agree with everything he writes. Thus, what would be the purpose of culling through Calvin's writings to find your opinions? As to being easier to read, I think the problem is that SOME of the Church Fathers were writing to different audiences, who understood the nuances of neo-Platoism and other pagan philosphies. But many of the Fathers are pretty clear about what they write.
It would cause me greater concern if 5 Cardinals came up with 8 different interpretations and then told me that I had to live by one of them. Especially if I knew it to be wrong.
So how do you "know" you are right? Again, you appear to be claiming infallibility for yourself. It is one thing to disagree with someone, but to "know" they are wrong???
