I can across the entry for Pre-Fall religions in Eclipse Phase, I had to roll my eyes a bit at the declaration that most of the Pre-Fall Abrahamic Religions would lose followers or would become ghosts of their former selves. It would be more accurate to say that certain sects of said religions would fall to near nothing or disappear completely, (the more escatological sects, with a rather Definitve Apocalypse having come and gone), but the non apocalyptic sects would more than likely adapt and move on. for a fairly large list of sects For Christianity: http://en.wikipedia.org/wiki/List_of_Christian_denominations For Jewish Sects: http://en.wikipedia.org/wiki/Judaism For Islamic Sects: http://en.wikipedia.org/wiki/Islamic_schools_and_branches A a mild thought on each religion's Sects (I'm not going to get into an argument on theology), those that are based on pligrimage to certain areas on Earth are going to have a VERY big problem adapting as Earth is a No Go Zone (tho might make for some lucrative runs for nabbing cultural artifacts), but the non-'place' based sects will probably add a few lines about moving out to the stars and the nature of the soul with Body swapping technology. I'm about to make a few generalizations and I am not intend to step on anyone else's toes but here area few observations on some of the Abrhamic Branches I see as being likely: Christianity: Roman Catholicism will survive from sheer inertia if nothing else as Apocalypse tends to bind people closer together to have SOMETHING to cling too. I imagine the First Space Pope Arising in the Jovian Belt and Encyclicals on Transhumanism (for the negative) being issued. There is also the possibility of a second Pope within system issuing counter encyclicals, making for interesting denomination conflict. The Eastern Orthodox Church will still be around in it's varied forms, tho I'm given to wonder if they may go back to a more spartan look given the evacuation from earth. The Oriental Othordox Church may not survive simply due to the relative lack of membership nations that might have easy access to spaceflight tech during the fall. Anglicanism will more than likely survive as it is not as Apocalyptic based and due to it's rather wide spread nature. Protestantism will also survive, if nothing else to Resist the authority of the Space Pope(s). Lutheranism I can actually see making a strong come back after the Fall, with a emphasis on community and looking out for each other, as well as fighting corruption on the metaphorical level (with the HyperCorps), and physical metaphysical level with TITANS viron suferers. Baptists are going to have a bit of a problem due to a lack of rivers or other places of baptism.....thought I suppose the common dunking ones head in a station "Shower" might work. I am not too familiar with this particular sect, so bear with me. Calvinism might sink it's claws into the Jovians as it is a rather strict and 'puritan' sect, and neo-Calvinist (Read: very old school, very humorless) zealots preaching against Transhumanity in all it's variations would not be surprising. The Later Day Saints Sect might be in a decent enough position to Challenge the new Space Pope if they are able to get enough people off planet. Given that Polygamy was a suppressed (but accepted) practice could give the LDS a edge in the Long Game. As to other sects of Christianity, I fear I have little familiarity with them, and will chose not to comment. Judaism: as Judaism by in large is not based on the concept of the End Times, it will probably whether The Fall better than most, as Judaism has had to deal with metaphorical and literal apocalypses in it's history more than once. Orthodox Judaism will likely adapt better than expected, but will have some problems with body swapping technologies (the medical advances, not so much), as downloading brings the question of the soul being copied. Expect a rather intense Rabbinical argument over the matter across all sects. The Segregation of Male and Females is also going to be thrown for a loop, but as this is the most traditionalist sect of Judaism (within reason, only recently were Hasidic Orthodox allowed to shave due to the electric razor), expect them to being on the somewhat lower tech end of encounters. Conservative Judaism is the middle ground of Judaism in that keep many of the aspects of Orthodox Judaism, with a note that Judaic law is flexible due to the times, but will try to conserve as much of the original intent as possible. Also they do not consider the Torah as the literal word of God. Given this flexability, this sect will be around after the fall in relatively (all things being equal) respectable numbers. Reform Judaism is what could be called 'progressive' and is more interested in following the moral laws provided by Torah as opposed to ritual. Given the relative lack of space provided for rituals on space stations, this sect should do rather well. As a Footnote, I would expect a holiday commemorating "Terra Diaspora" to be added to the Holy Days in the Jewish Calender after the Fall. Will expound on the Islamic sects after getting some rest Conservative Judaism
