Our priest did his entire homily on the discussion between Jesus and Pilate about truth. Except instead of staid platitudes, he started spitting fire about how popular culture rejects universal truth about biology and thousands of years of common sense, and how it was the duty of Catholics and Christians to loudly reject this. If you reject the truth, then you reject Jesus.*
He later quoted writings from Pope Benedict about how moral relativism is the biggest threat to the world. He also said this moral relativism has even infected the churches under the guise of tolerance and acceptance.
