Normally, I would keep this private, since I am not inclined to stir up sectarian debates between the two or three parts of the shattered church; but since several people on this website have said I was Catholic, and since I corrected them and said I was not Catholic, I did not want anyone who trusted me what I said that, to be surprised when that information turns out to be out of date.
For my Protestant friends, all I can do is assure you that that Church you broke away from in centuries past has been reformed of the abuses you complained of at that time. The Pope no longer sells indulgences. The theological differences are minor enough that Christly love, if you imitate His love, will cover them. I was raised Lutheran, and drank in anticatholicism with my mother's milk, so I assure you I am aware of most or all the objections, subtle and obvious, which you consciences in good faith might raise. The shock that came to me when I looked into Catholicism is that the Catholics do not teach what my teachers told me they teach. In any case, Protestant friends, I will be closer to you than I was when I was an atheist, so please consider this progress.
For my pagan friends, rejoice! My Protestant friends tell me my Catholic friends are pagans anyway! So I will be closer to you than I am now. And there is certainly some truth in the idea that Catholicism is a child of Jewish and Hellenic thought: the ancient civilization of Europe is still alive in the Catholic Church. If you worship Brigit, and I revere St. Brigit, this will be a common bond between us.
For the Atheist friends, give thanks! You may think of Catholicism as the most backward and obscurantist of the Christian sects. Not so! Not only does the Catholic Church acknowledge Darwinian evolution, the approach of at least some of the writers (St. Aquinas, for example, or St. Justin Martyr) is as rigorous and as rational as even the best of atheist writers, and darn mile more clear and rational than the worst of atheist writers (who are the only ones we hear about these days). Catholicism, in many of its branches, is not given to the religious enthusiasms of revivalism that so many atheists find disquieting. (Whether this lack of revivalism is a good thing or not, I leave for the reader to decide. Certainly more enthusiasm and crusading spirit would not be a bad thing for this Church at this hour of history.)
