Everything is technology in a sense. It's not a very helpful category. The way I like to define technology is "something created by man, which in turn shapes man". While I would argue that _certain_ religions are not man-made, making them not technology, I agree that many are.

What religions in general have in common is more than just a social dimension (law, language, music, and technology in general are all social). Rather, they all involve an orientation toward a Transcendent Good, whose aim is to free adherents from the problems of the mundane. Some religions do a better job at this than others, depending on the reality of the transcendent good they point to, and how successfully they maintain a pure form of that doctrine.
