Yes, many of these questions are answerable and answered in the Holy Scriptures when the scriptures are read in context of the entire witness of scripture, with the proper distinction of law and gospel applied.
Other questions are not answered, and with these God expects us to listen to our consciences, informed by the scriptures, to employ our freedom in Christ responsibly.
Perfect!
So, what ARE the answers?
For it is in the answers to these very questions that we find the practical distinctions among the denominations today. One can use the answers as a roadmap to the denominations, and find the Church that most closely believes what one believes to be true.
It's great that the Bible answers these questions. I think it does too. I doubt that what I think the Bible means on these issues will correspond to what you think it means.
That was my point in listing the questions. In the modern world, most American Christians really don't understand or care about the theological debates of the 4th Century. They are abstractions. But the legal, ethical and moral debates of our own century - everybody cares very much about these, and the Christian denominations all answer these questions differently. These modern issues, and not ancient abstractions, are what practically separates one denomination from the other.
Catholics, the Orthodox, Anglicans, Lutherans, Presbyterians, Baptists, Mormons, UCCs, Jehovah's Witnesses and Quakers all have different sets of answers. All read the same Bible (more or less) and all pray to the same God, but they don't agree on what the Bible means, or what God intends.
I asked the questions to flush out into the open the fundamental political issues whose answers divide the modern Christian world.
