Remathilis
Legend
It should be noted the RC language (which appears in the All New Black Box as well) was probably an attempt to remove the BADD elements of from Basic to make it more kid friendly. Basic has almost no planar stuff until you get to the Immortals level, no Gods (with Immortals filling a semi similar role) and not tying clerics to them (especially with no explicit mechanical consequences for losing your faith).Basic clerics have varied.
Here is from Moldvay Basic:
"Clerics are humans who have dedicated themselves to the service of a god or goddess. They are trained in fighting and casting spells. As a cleric advances in level, he or she is granted the use of more and more spells. However, clerics do not receive any spells until they reach 2nd level (and have proven their devotion to their god or goddess)."
It then however never mentions gods again.
Here is from the Rules Cyclopedia:
"A cleric is a human character who is dedicated to serving a great and worthy cause. This cause can be an Immortal being dedicated to a specific goal or attribute; sometimes the cleric is serving only his alignment, and has no interest in immortal beings. The D&D game does not deal with the ethical and theological beliefs of the characters in the game."
"All clerics belong to orders, or clerical societies, made up of clerics serving the same ends. A brand-new cleric character is at the very bottom of his clerical organization; as he gains experience levels, he will also gain new powers and responsibilities pertaining to his clerical order. The DM will decide, and will inform you, how the clerical orders of his campaign are arranged."
It is interesting that the powers gained are specifically pertaining to the order, implying they are taught or unlocked, not granted.
Later in the RC it says this about deities:
Immortals and Deities
The Immortals of the D&D system and the deities of the AD&D system should not be converted between the game systems.
Still, the change from Moldvay's god's to Alston's worthy cause is significant because it does mean the cleric's identity is not inexorably tied to a God or divine being, nor something that can be given or taken away.
