One aspect of my low-ish magic setting is that clerics (and other divine classes) are scattered throughout their mostly expert-classed priesthoods... however, their divine powers may desert them from time to time, leaving them unable to cast real spells for months, years, decades at a time. So clerics can't count on being fully powered clerics their whole lives. It comes and goes.
I assume that, for PCs, clerical divine powers are operative for the duration of their adventure. I don't use this to screw around players. But adventures are episodic, so there may be a year or two between quests, and the PC cleric's power may be said to recede during that time.
