The concept of Purgatory is comfy

after the toll houses, of course

Is it therefore safe to say that if we don't enjoy going to church on earth, we won't enjoy heaven?

Yes. Assuming you go to heaven which would be unlikely.

Harsh..

Now, the chapter and verse, if you wouldn't mind.

I won't say Toll Houses are "Gnostic" like some. But they go back farther than that and are equally stupid: It's Mithraic. And really, older than that: The Mediterranean was obsessed with trials and labyrinthine like structures to initiate people. This is another form of it, with Christian/Semitic trappings involving demons. Orthodox need to stop pushing this. It's pagan and for old goy cultures who should be lost to history already.

And consider this: If it was so crucial, it'd be in the Seven Councils. But the afterlife is one of the subjects where Church fathers (peacefully) debated and disagreed on and didn't make All of the Specifics a rule of faith (this is a Roman Catholic trait. Not Orthodox).

That's because you don't understand the gospel

Not really. In Church Jesus is literally there with everyone. If you aren't enjoying God's real presence here on earth, why would He allow you in Heaven?

And neither do you.
