Written by one 'Robert Barron is the auxiliary bishop of Los Angeles'

A masterpiece in misconstruction and misinterpretation.

Consider:
"opening verse: “Imagine there’s no heaven / It’s easy if you try / No hell below us, above us only sky / Imagine all the people livin’ for today.
I frankly can’t imagine anything worse. To say that there is no heaven or hell is to say that there is no absolute criterion of good and evil. ...."

So, belief in heaven and hell means belief in an "absolute criterion of good and evil."
What absolute criterion would that be, auxiliary Bishop? And of course all religions are consistent in their definition of good and evil, aren't they? No, they aren't.

Even better one :

"... If you doubt the convictions of a Roman Catholic bishop, take a good hard look at the tens of millions of corpses piled up in the last century by people who took very seriously the proposition that there is “no hell below us; above us only sky. ...."

Does he mean people like Adolf Hitler, the Catholic, who went to a lot of trouble to steal the Spear of Longinus, which supposedly pierced the side of Jesus, apparently because it has magical power properties to those who have it?

How anyone could see Lennon's song as an anthem for authoritarianism is just astonishing. But he reveals himself, this so called auxiliary Bishop. Lennon catches in that song a secular future ideal, free of warring countries, no longer fooled by the stupidity of religion, and many of us identify with it. This sort of Bishop knows this and is frightened by it. Good.
