What is the origin of the religious term "creed?"

The term
"creed" is often used in religious contexts.  For example, there are the Nicene Creed
and the Apostles' Creed that are used in Catholic churches as well as in some other Christian
churches.  These creeds are statements of belief in which the congregants are affirming that
they believe in the things that their church doctrine says that they should.

This makes sense because the word "creed" comes from the Latin.  It comes
from the word "credo" meaning "I believe."  The Latin versions of the two
creeds mentioned above both start with this word.  This is a conjugation of the verb
"credere" meaning "to believe."
