You failed to explain why you thought wisdom makes more sense and why charisma doesn't for any spellcaster.
Because when I look in 5e PHB, under cleric I read;
"Harnessing divine magic doesn't rely on study or training. A cleric might learn formulaic prayers and ancient rites, but the ability to cast cleric spells relies on devotion and an intuitive sense of a deities wishes."
There is nothing illogical in there (within the game framework), and there is absolutely nothing that evokes charisma.
It later goes on to explain their role as "divine agents" which it says can involve braving dangers..., smiting evil, or seeking holy relics. It says many clerics are also expected to; protect their deities worshipers which can mean fighting, negotiating peace between warring nations, or sealing a portal. It says most adventuring clerics maintain some connections to established temples and orders, and they might ask for a clerics aid.
There were several places in there where it would have the obvious choice to put in something about some role in gathering more worshipers, preaching etc. but they chose not to and yet the class makes perfect sense. That simply is not what the standard cleric in 5e is meant to be, and certainly not how they work their magic.
Your argument seems to be essentially "To me, the basic D&D cleric should be about charisma and gathering more followers for their god. With a sub-argument being that how good the cleric is at that the more power their god will grant them." None of that is true in 5e, and certainly wasn't the standard in the past, so there really is no basis for your argument. If you want to make a cleric with high charisma that is about gathering new followers that is fine, and if you want to decide that gods grant power is some way based on that it is also fine. Suggesting that is in any way more logical or true to some archetypal D&D cleric isn't really.
The majority of clerics in games that I have been involved in have been (over the course of decades) insightful, wise, and more aware of the world and people in it than the average person. They have typically been much more reserved and introverted than the bard or paladin, and less likely to try to convince others of anything (they would typically rather rush off to save someone than try to spend time trying to convince others to help). Now, I am not saying that our way is somehow the quintessential D&D cleric, but it does happen to work well with a wisdom primary whereas a charisma would be a difficult stretch (certainly not 600% better).
