There has been for some time an idea that eventually Christianity
would put aside their differences and merge into one super-religion, pulling up aspects of each and perhaps dominating the Earth. It has been suggested, even, that the somewhat more polytheistically inclined Hinduism
could absorb both, and what the heck, throw Judaism
into the mix, thus creating for the first time in recorded history a single religion commanding the fealty of a majority of the world's population. The idea is given to several different authors, who have taken different angles -- Arthur C. Clarke
for example writes in his 1992 The Hammer of God
(not to be confused with the Led Zeppelin
biography Hammer of the Gods
) of a not-so-far-future fictional Earth where "The sudden rise of Chrislam had been traumatic equally to Rome
...." growing swiftly to a hundred million adherents, abetted by cultural and economic difficulties squeezing the parent faiths.
But as a matter of practical experience, consolidation
is an unlikely path for any major faith; each is more likely to split into multiple smaller sects, and any reconciliation between sects of different faiths will tend to be far outside the mainstream of beliefs falling under the umbrella of the faith. And so, even as there are conciliatory voices today who would claim that all these different faiths are simply different paths to the same Creator, (indeed a position held, if somewhat more obliquely and indirectly by Pandeism
), the greater tendency amongst the faithful is to ramp up greater indictment against beliefs discordant to their own. Even if, it turns out, those faiths fall under the broader ends of the umbrella of their own religion.
There is in fact, by the way, a faith group operating under the name 'Chrislam' and purporting to carry out the idea discussed here, attempting to meld assertedly reconcilable elements of Christianity and Islam. Or, actually, there are two groups. Both are in Nigeria
. Oh, they started out as one, but had a schism
somewhere along the way and are now, if not bitter enemies, passing acquaintances who don't pass up an opportunity to snipe
at one another's divergent doctrines. Ironically, if unsurprisingly, this is what Arthur C. Clarke forecast for his fictional version as well.
