Catholicisms

Contrast the medieval Catholicism of Poul Anderson's The High Crusade (see here) with the modern and future Catholicism of Julian May's Pliocene/Intervention/Galactic series.

Denis Remillard, while confessing to a Jesuit priest in 1995, mentions that he values highly the opinions of two colleagues, a Neo-Marxist and a Tibetan lama turned idealistic humanist. The priest comments that, in both of those faiths, the good of society is paramount over that of the individual whereas Christianity and Western civilization give the individual sovereignty in reproductive matters, which is the issue that they are discussing. Thus, a reasoned exchange between alternative world views is possible.

Later in May's series, a woman Jesuit priest officiates at a same sex marriage. That will not happen in our timeline.
