If that were creation, there wouldn't be a lovely third column explaining which bigger world religion or religious / spiritual system they were part of. Hardly any of those new religious movements are 'creations', almost all of them evolved within a clear pre-existing context and still function within a larger system of beliefs. Scientology and the Moonies are obvious exceptions to that rule.
But fine, let's look at one religion then: christianity. Christianity started out as a tiny jewish cult, went on to become proto-gnostic, gnostic, dualist, orthodox, platonic, catholic, protestant/reformed, contrareformed, literalist,... Over 2000 years we've had sudden, jarring changes like the reformation/contrareformation or the eastern schism, Vatican II or papal infallibility; as well as slower evolutions like the evolution of the concept of heaven/hell/limbo, the concept of the sacraments, the ontological status of the eucharist, the dual/divine nature of Christ and the relationship between religion and science. Not to mention more recent phenomena like vôdou and Santeria, Jehova's Witnesses, the pentacostal churches, the Church of LDS, liberation theology and the recent popes' efforts at ecumenism.
Religion is absolutely known for change, or it wouldn't exist anymore. It adapts to time, circumstance and need.
So, to get back on-topic: western catholicism is changing, and the biggest question is: is the Church going to accommodate for this change, as it has in the past, or are catholics going to reform into 'new' churches. I don't know what I hope for most, exactly, I just hope that change manages to push through both internal and external obstacles.
