Lyrics from his 1971 song "Imagine":
Imagine there's no heaven, it's easy if you try.
No hell below us, above us only sky."
In a 1965 Interview:
"Christianity will go. It will vanish and shrink. I needn't argue with that; I'm right and I will be proved right. We're more popular than Jesus now; I don't know which will go first - rock and roll or Christianity."
"I believe in God, but not as one thing, not as an old man in the sky. I believe that what people call God is something in all of us. I believe that what Jesus and Mohammed and Buddha and all the rest said was right. It's just that the translations have gone wrong."
1971 interview by Tariq Ali and Robin Blackburn:
Tariq Ali: Your latest record and your recent public statements, especially the interviews in Rolling Stone magazine, suggest that your views are becoming increasingly radical and political. When did this start to happen?
John Lennon: ... In my case I've never not been political, though religion tended to overshadow it in my acid days; that would be around '65 or '66. And that religion was directly the result of all that superstar shit--religion was an outlet for my repression. I thought, 'Well, there's something else to life, isn't there? This isn't it, surely?'
Later in the interview:
... At one time I was so much involved in the religious bullshit that I used to go around calling myself a Christian Communist, but as Janov says, religion is legalised madness. It was therapy that stripped away all that and made me feel my own pain.
... Well, his thing is to feel the pain that's accumulated inside you ever since your childhood. I had to do it to really kill off all the religious myths. In the therapy you really feel every painful moment of your life--it's excruciating, you are forced to realise that your pain, the kind that makes you wake up afraid with your heart pounding, is really yours and not the result of somebody up in the sky. It's the result of your parents and your environment.
As I realised this it all started to fall into place. This therapy forced me to have done with all the God shit. All of us growing up have come to terms with too much pain. Although we repress it, it's still there. The worst pain is that of not being wanted, of realising your parents do not need you in the way you need them.
... Most people channel their pain into God or masturbation or some dream of making it.
... It's a bit of a drag to say so, but I don't think you can understand this unless you've gone through it--though I try to put some of it over on the album. But for me at any rate it was all part of dissolving the God trip or father-figure trip. Facing up to reality instead of always looking for some kind of heaven.
