This is not against the U.S. Religious Right, mainly Christian, but with a few Orthodox Jews along for the ride, and even, for political reasons, a few Muslims.

This is against the Religious Center and Left, as well as Right, of all religious traditions that believe in praying to a god(dess) to get him/her to change their minds.

Via Tales of Whoa, who says (rightfully) that even within the world of religiosity, with the Western dual-omni god, at least, this is one that doesn't make ANY sense, we have this in-depth research test.

It checks all the scientific boxes:

Remote

Random

Double-blinded.

People were asked to pray for COVID patients' recoveries. And it made no difference.

Zip. Zilch. Nada.

Summary details:

The objective of this study was to evaluate the effect of intercessory prayer performed by a group of spiritual leaders on the health outcomes of hospitalized patients with Novel Coronavirus (COVID-19) infection, specifically focusing on mortality and hospitalization rates. Design: This was a double-blinded, controlled, and randomized trial conducted at a private hospital in São Paulo, Brazil. Interventions: Both groups continued to receive their usual medical care in accordance with HCor Hospital's institutional patient care protocol for COVID-19 patients. Intervention: Both groups received their regular medical care according to HCor's institutional patient care protocol for COVID-19 patients. The intervention group, in addition to standard treatment, received intercessory prayers performed by a group of spiritual leaders. Main outcome measures: The primary endpoint was in-hospital mortality. Secondary endpoints included the need for mechanical ventilation during hospitalization, duration of mechanical ventilation, length of ICU stay, and length of hospital stay. Results: A total of 199 participants were randomly assigned to the groups. The primary outcome, in-hospital mortality, occurred in 8 out of 100 (8.0 %) patients in the intercessory prayer group and 8 out of 99 (8.1 %) patients in the control group (HR 0.86 [0.32 to 2.31]; p = 0.76). Additionally, there were no significant differences between the groups in terms of secondary outcomes. Conclusion: The study found no evidence of an effect of intercessory prayer on the primary outcome of mortality or on the secondary outcomes of hospitalization time, ICU time, and mechanical ventilation time.

A total of 199 patients is relatively robust, too, at least partially undercutting "small sample size" claims.

As for the theology, philosophy of religion and related?

This issue hits home hardest with the classical Western monotheisms, post-early Jewish contact with Greek philosophy. In other words, the "dual-omni" god, as I call him, both omnipotent and omnibenevolent.

But, this critter doesn't even have to be omnibenevolent. Only the first omni is really in play, as long as omniscience is understood as a subset of omnipotence.

So, you have a deity who already knows what is going to happen because, and in addition to he (she, it) having already created things to happen and play out that way. And yet, you're praying for him to change his mind.

After all, the Torah records Moses himself as saying, in Numbers 23:19:

God is not human, that he should lie, not a human being, that he should change his mind.

There you go.

BUT?!

After the Great Flood, when Yahweh smells Noah's burnt offering, although Genesis 8:21 doesn't use the actual word, he is said to have "repented" of what he did. Of course, before that, in Genesis 6:6, he "repented" of having created human beings in the first place, and there, the Hebrew word is used.

Beyond that, in Genesis 8, Yahweh is just as much quasi-human as Zeus, as he "repents" precisely because he SMELLS Noah's burnt offering.

Fact is, of course, as this illustrates, there is no theology of the Bible, or of the Tanakh or New Testament. Nor even of individual books that have gone through multiple writing and editorial hands.

Of course, there is, in Isaiah, the passage, II Kings 20, when Hezekiah is told that his illness will kill him and he prays and gets 15 more years of life.

I guess believers in an omnipotent god could say this was his own plan all along and he just didn't make that clear. In other words, per Job as filtered through Paul in Romans, this is god's inscrutability and y'all on earth just need to shut up.

Well, as I have called it, that's the psychological division of the problem of evil, so you just opened a bigger can of worms. And, per what started us off? The more liberally religious, at least in Christianity, as well as the wingnuts, ultimately go there.

Or, also among the semi-liberal theologically, but something also used by religious fundamentalists there's C.S. Lewis, whose essay "Does Prayer Work" Tales of Whoa cites. Lewis says, in essence, that in a scientific test mode, this isn't real prayer. Gee, don't we have psi phenomena people claim exactly the same when telekinesis, etc., are subjected to scientific testing?

But, Lewis and the wingnuts are wrong anyway, as the study allowed for exactly that:

The intercessors consisted of Protestant religious leaders who were selected based on their faith, availability, and commitment to daily prayers for a specific period. They were volunteers from Protestant congregations across various cities and denominations. The theological knowledge of each intercessor could not be objectively evaluated, but their voluntary participation and shared belief in the efficacy of prayer for the sick were significant factors in their selection.

Your last door is closed.
