The author is correct about War of the Worlds. My Dad recalled being in church when some people burst in and rushed up the aisle begging for help from God! [During the original radio broadcast, naturally.]
The H. G. Wells story is decidedly atheistic, and even anti-religious, in its import. Just read Chapter 13, "How I fell in with the Curate" to see this. The Curate, far from being steeled by his faith, loses all grip and becomes a continual burden on the narrator.
In Chapter 4 of Book 2, "The death of the Curate", he can't control his ravings while they are in hiding and meets an ignominious end.
