AA / Alanon / Alateen
Aherents may claim it is not a religion, but it starts with despair, puts you in touch with a higher power, offers salvation, uses public confession, depends on evangelism, and it works. The catch is you have to be an addict or connected with an addict before you can join.

Astrology / Space

Buddhism
The Buddha started with suffering and went on until he saw that we invent our selves. He did this in N. India in about 2,500 BC. Ever since, his followers have been finding ways of passing on this message and teaching meditation, which was part of his Hundu tradition. Inevitably in all that time, there have been splits, but Buddhism is a non-violent religion, so its followers do not fight.

Christianity
Jesus taught that people should love their enemies and that God is in them. He also lived out his message, dying a hideous death in Jerusalem in the latter days of the Roman Empire. He was Jewish and his followers claim that he rose from the dead and was the Messiah the Jews were waiting for. They became the Church, which has many branches and offshoots.
