By the way, like most Catholics, I used to think that the Protestants generally have a good grasp on the scripture, till I discovered this cavalier attitude to all but isolated prooftexts. In one of his sermons Luther admitted to the parables being a complete mystery that we should not attempt to understand. Not surprisingly, it was the parable of the rich man asking how to inherit the Kingdom of Heaven, and Christ answering, essentially, "by your works of love and dedication".
I have noticed a lot in these forums recently that certain challenges to Protestants go unanswered, my guess is that they lack a "pre-packaged" response to it.
I was asking last week why it is that God would devise a plan for Salvation that involves reading the Bible when the that would be nearly impossible for nearly everyone for almost fifteen hundred years after his death when the printing press was invented. After a few of us remarked about their avoidance of the question, they all collectively seemed to agree that God had just planned it that way.
