On second thought, maybe not.
Jimmy Little got to No. 1 in Sydney and No. 3 in Melbourne with ‘Royal Telephone’, previously done by Burl Ives.
‘You may talk to Jesus on this Royal telephone’.
The Highwaymen’s rendition of “Michael Row the Boat Ashore” made #1 on the Hot 100 in 1961, and “Dominique” by The Singing Nun topped the chart in 1963.
Louis Armstrong - “When the Saints Go Marching In.”
Does that count?
Does Fire by The Crazy World of Arthur Brown count? I mean, he does claim to be the “God of Hellfire”.
Paddy McAloon of “Prefab Sprout” contemplated Love, Elvis and God in one of my favourite albums. “Jordan, the comeback”. Religion was woven right through it and there were several top 40 hits from it but the most overtly religious songs are album tracks such as
“doo wop in Harlem”
“one of the broken”
“mercy”
Now I don’t give a fuzzy bollock for religion per-se but happy that great art gets prompted by whatever people feel deeply about.
I was going to make everyone vomit and mention Dear Mr. Jesus. But a check of Wiki says it only made it to #61, thus disqualifying it for this thread.
You’ve all been spared! 
Apparently “Pray” by MC Hammer made it all the way to #2 in some charts. Unequivocally religious.
Less clear: **“God Only Knows” **by the Beach Boys
U2 actually has a few of these. In addition to ‘40’ and ‘I Still Haven’t Found What I’m Looking For’ we could include ‘Gloria’. It sounds like a song about a girl but it’s Latin.
‘Pride (In the name of love)’ references Christ, Jonah and Judas in a verse.
A very catholic young man, our Bono.
If you want to marvel at how much the UK charts of changed over the years, check out Lena Martell at number 1 in 1979, with One Day At a Time.
Lena Martell on Top of the Pops
Look at that studio audience, awkwardly shuffling around. They’d been hoping for The Jam or The Police… and they got Lena Martell.
It doesn’t get much more religious than that.
Until, of course, twenty years later, along came Cliff Richard with his Millennium Prayer
Heart Like Mine by Miranda Lambert was number one on Billboard’s Hot Country Songs and 44 on the Hot 100.

If it does, then every recording of Dem Bones should count, too.
In case you don’t know, this is the song with the verse with all the “—bone connected to the — bone”:
I was surprised to learn that the song is a spiritual, with biblical roots:
How many recordings of Dem Bones hit the Top 40?
I first heard it on The Munsters.

BTW, Louis Armstrong’s version of “When The Saints Go Marching In” hit the Top Ten.
I have no idea how high Fred Waring’s version charted.
But the criticism is irrelevant to my comment.
I believe the request is for overtly religious songs that hit the Top 40.
TEEN ANGEL, from back in the 60s.
And how about JESUS TAKE THE WHEEL, by Carrie Underwood.
I was commenting on the suggestion that “When the Saints go Marching In” being eligible by virtue of being religious. I had no idea that any version might have broken the top 40. I figured Dem Bones was as familiar a song as Saints, and was commenting on that basis. I was unaware that Armonstrong’s version broke the Top Ten. I still haven’t verified this.
I thought that was about an NFL team.
