If by 'occult' you do just mean 'hidden meaning' then Mysterious Ways. I seriously doubt most people listening to one of the bands most recognizable tracks know it's Herod Antipas mocking the faith of John the Baptist before he decapitates him.
I have never heard that before 
An interesting discussion here on the meaning of the song including what you are suggesting:

I don't know where I originally heard it, but once you do hear it, you can't unhear it.
U2 was fascinated by Oscar Wilde (Dorian Gray reference for example on BOY), and they wrote
Salome as an ode to the Oscar Wilde play of the same name. Salome was the woman who performed a sexy dance for Herod (she's not named in the Bible but she is named in Jewish history) before she asked for the head of John the Baptist. Oscar Wilde's
Salome included the
Dance of the seven veils, which was recreated on Zoo TV by Morleigh Evans. In Oscar Wilde's Salome, the moon watches over everything. So Bono's altar ego in Zoo TV is Herod Antipas, sword in hand, telling John the Baptist it's all right that he's about to be executed because God's Holy Spirit moves in mysterious ways.
There's other clues too. Wilde quotes St Francis of Assisi's "Canticle of the Creatures" in which the John's brother is the Sun and his sister is the moon.
John is "running away from what you don't understand". In the Bible, John the Baptist doesn't understand Jesus gospel and never actually becomes a disciple.
This theme is repeated in the songs Salome and If you wear that velvet dress.
To me, it's one of the great U2 hidden lyrics of all time. Another example of this kind of double entendre is of course Until the End of the World, which is about Judas Iscariot meeting Jesus on Judgement day, and I think most of us know that one. Another similar one is "Wave of Sorrow", which ostensibly about the Ethiopian famine, but has a clear message of faith/doubt related to the 'holy land' origins of Ethiopia and the legend that the Ten Commandments tablets ended up in Ethiopia. Another similar one is Flowering Rose of Glastonbury, which is about Arthurian Legend which claims that Jesus survived his execution and was taken to England by Joseph of Arimathea, landing on Glastonbury and proving his divine credentials by making his staff flower with a white rose. (Inspired by the song "Jerusalem", lyrics by William Blake)
I do appreciate Bono's lyrical depth, though it's been more lacking in recent years. None of these songs were written in the last 15 years, and the last two albums don't have those double-layered lyrical depth unless I am missing it. Even where they had depth, like Sleep like a Baby Tonight, or Book of your heart, it's a little more obvious.
