Need help Googling: Stages of religious maturity

Hello all...

I've been Googling for a while and can't seem to find what I'm looking for.

Hopefully someone here can help.


I remember reading once about the stages that religions go through as they get older.

Basically, the infancy of said religion and the practices contained within.
The "teenage years" of religions and how the practices have changed...
The middle age years of the religion and the practices...etc..


Any of this ringing a bell?
Can anyone point me in the right direction?
