Notforsale,
Is Jesus the Christ, the Son of the Living God?
Did the glory of God the Father raise Him from the dead?
Do people who believe on Him have the promise of everlasting life?
If your answer is yes, then you accept as true things which you cannot prove, thus making your earliest comments false.
If your answer is no, then you are indeed backslid (if you ever once embraced these concepts as true).
Salem witch trials and whatever else doesn't matter. It's a rabbit trail, a red herring so you can avoid the issue.
Trying to make a case against Revelation's early canonicity is also bogus. Just because Jerome and Gregory of Nazianzus doubted it in the mid to late 4th century, doesn't mean it wasn't generally accepted well before then, because it was.
So you can quote Denzinger all you want and cast doubts on the autheticity of the book if you like. But it doesn't make it so, and it's not the only book of the Bible that fully comments on the hope of resurrection and eternal life in Christ in heaven.
And that's what you're avoiding, refusing to deal with.
Jesus specifically mentioned "the world to come" in
Luke 18:30, that is the coming age/aeon of the New Jerusalem.
Do you believe the words of Jesus or not?
