The problem lies more in the fact that the subject matter of which we speak is living history, as opposed to a reflection, study, and comment about past events.
Christianity is still around in full force, and therefore is not so easily discussed as say Zeus, Baal, Molech, etc. We can almost assuredly find few, if any, individuals who practice those religions. Because of this we can look back and debate with little obstruction.
I myself am a Christian, but having been immersed in professional studies and surrounded by individuals from all walks of life (Theologians, Historians, Scientists, etc.), I am accustomed to seeing the debate over Iesu Christi continue to the point of absurdity. I am also used to those who see the futility of my faith. It doesn't bother me to hear someone mention my convictions as lacking (or in many cases much more profane language).
The fact of the matter is that we can debate this for hours on end, neither side having gained ground because both exhibit faith in their views. For a Christian, the events surrounding Yeshua are of a supernatural divine nature, therefore the impossible is possible. To others it is a matter of opinion as varied as the denominations that claim to follow Him.
I have to drive an hour to a lecture so I will hopefully be back soon to post more. I've been terribly busy as of late, and for that my apologies.
Keep the discussion civil and remember that everyone's views are their own. Discuss, do not command
