While the Catholic Church has been absorbed with saints and souls this time of year, much of the Protestant world has been observing Reformation Sunday, a commemoration of Martin Luther posting the 95 Theses.
Setting aside the merits of his claims, it is interesting to look at how well his teachings have done in the half-millennium since they were promulgated.
In Germany, Christianity is a spent force, and those few identifying it do so with practices that Luther himself would abhor - female clergy, legalized sodomy, and a general repudiation of the old teachings. Interestingly enough, this love of sin and vice afflicts Protestant and Catholic alike. Must be something in the water.
But elsewhere, we see the same symptoms. I believe many of the old 'state churches' have been disestablished, but even if they haven't, are any of them following their original theology, or have they embraced modernity? I think almost all of them lie on the most liberal end of the religious spectrum.
Mainline Protestantism in the United States has likewise collapsed into meaningless tropes, rainbow flags and an inability to define sin outside of "hate," which of course is the worst thing ever. Female clergy can cheat on their husbands, divorce them, have open relationships and remain in good standing as they explore their "inner goddess."
The Church of England, with its separate roots, held together much better, but it has also splintered, first as the Methodists broke away, and now as the Anglican Communion has been torn asunder.
If one believes that the fruits of one's actions indicate their conformance to the will of God, then Luther's reform has failed. The lands where it first took root are desolate, and the crop from its transplanted seeds is rancid and twisted. Only a fraction of the harvest is wholesome.
Christianity has faded throughout Europe, and it has all but collapsed in Ireland, but elsewhere its seeds continue to flower. There are more Catholics at Mass than Anglicans in England, and Scandinavia now boasts a small but growing Catholic community.
Maybe the branches of the Sixteenth Century German Church were already rotten, which is why they fell away so quickly. There does not seem to have been the same level of clerical resistance in northern Europe as there was in Tudor England.
