You all ask too much from my last post, methinks. The title was "Problems with Protestantism," not "Problems with Protestantism and how they are answered by a concise and accurate Catholic Systematic Theology."
Taken together, the comments seem to indicate a demand for a more detailed look at Catholic doctrine, and while I would love to meet that demand, it is something I feel neither prepared nor qualified to write at this time. However, I would loathe to leave these questions unanswered, and so I have arrived at the following solution: I will serve as an aggregator.
It is my intention to pick a doctrine and compile a list of sources that you can read to learn more about it, along with a brief summary of the sources, each week. Whether or not I will stick to that schedule is a different matter entirely, but I'll try.
For now I offer you this, leave me a comment with ONE question on ONE topic and I will do my best to answer it.
