Happy Easter McTraveller
I'd say from an outsider's perspective that your last sentence is inaccurate, that the more important justification of religion is not based solely on that event, but how JC does good through you. I confess, in my youth I was angry at the local Christians for what I considered at the time their domineering and exclusive nature, and this also drove my father in his youth and thus myself forth from the religion of my grandparents. I have learned since that it is not the precepts that are to blame, should they be led by example rather than imposition, but that the falsehoods of man and willingness to forget these lessons in empathy leads to a drive to domination which is the bane of such individual (heretics?) as much as to those who are victims of such.
If I may recommend a book that changed my view, it would be the novel Quo Vadis. There was no work I have encountered that has softened my heart against practictioners as this one, though I reserve the right to be critical of individuals seeking to impose through authority or force their own beliefs in ways of living harmlessly, to the point I am reminded of St. Justin's First Apology. If I may tender a joke through role reversal, at times I almost feel as, an outsider in a very conservative Christian area, the barbarian princess in Quo Vadis. While this is a burden of questionable weight that I bear and have very much overstated here, I still will do my best to choose forgive this, as I feel this is a reflection of an excellent tenet.
So, happy Easter to those who care for the poor, service the unwanted, welcome those who are different, and do good deeds in the name.
