One very famous song in the Philippines about the hipocrisy of religious people is Banal na Aso, Santong Kabayo..

Banal Na Aso, Santong Kabayo

Kaharap ko sa dyip ang isang ale
Nagrorosaryo mata niya'y nakapikit
Pumara sa may kumbento
Sa babaan lang po sabi ng tsuper kase me naghuhuli
Mura pa rin nang mura ang ale

Banal na aso, santong kabayo
Natatawa ako hihihihi
Banal na aso, santong kabayo
Natatawa ako hihihihi
Sa 'yo

Nangangaral sa kalye ang isang lalake
Hiningan ng pera ng batang pulubi
Pasensya na para daw sa templo
Pangkain lang po sabi ng paslit
Talagang di ba pupwede?
Lumipat ng pwesto ang lalake

Banal na aso, santong kabayo
Natatawa ako hihihihi
Banal na aso, santong kabayo
Natatawa ako hihihihi
Sa 'yo

Anuman ang iyong ginagawa sa iyong kapatid
Ay siya ring ginagawa mo sa akin

Banal na aso, santong kabayo
Natatawa ako hihihihi
Banal na aso, santong kabayo
Natatawa ako hihihihi
Sa 'yo

Translation in English is below..

In front of me was a lady
Praying the rosary with her eyes closed
She asked to be dropped off at the convent
The driver replied "To the rightful unloading area lest I'll be caught."
But the lady started cursing.

Chorus:
Holy dog, saintly horse
I am laughing, Hi hi hi hi
Holy dog, saintly horse
I am laughing, Hi hi hi hi
At you.

A man is preaching on the streets
A beggar boy asked him for alms
"I am sorry," he said, "This is for the temple."
And the child begged, "Just for my food, please,
Can you not give me anything?"
But the preacher moved somewhere else.

Repeat Chorus

Whatever you are doing to your brothers
Is what you are also doing to me.

Repeat Chorus
*** The song is about the irony of people pretending to be holy when their acts are obviously in contrast to what they project to be, or preach.
