I'm really not at all interested in getting into a verse- matching competition. A few verses that point towards the salvation of all creation jabs been posted - there are more. Posting verses at each other won't resolve the debate.
Having re-read this thread, I cannot find any references to scripture which support, even tentatively, the doctrine/ denomination of universalism.
But you are correct - quoting verses at each other will not resolve this discussion.
So this begs this question what is the origin and purpose of universalism? Universalism presents 2 problems for bible believing Christians:
1) It rejects the doctrine of Hell
2) It upholds that non-Christians will be saved through Christ (pluralism)
Without getting in to specific verses, but from a reading of scripture as a whole, there numerous references to the fact the Christ is unique and that salvation is through Him alone. He is The (only) Way, The (only) Truth and The (only) Life.
You need only read Pauls epistles to establish this.
You need only read The Sermon on the Mount to establish what Jesus taught us about Hell (Gehenna / Tartarus / Sheol / Hades etc)
So without fiddling around with specific verses (normally taken out of context) and instead reading entire books and understanding the history, setting and context of how they were written, I do not get any indication that all would be saved.
It's a nice idea, and one that I'd love to be true - certainly when I think of family members, BUT I cannot reconcile with my own (albeit infallible) interpretation of scripture.
Christopher Hitchens was still holding on to his atheism on his death bed, hours before he died. I'm not ruling out a change of heart, but it seems unlikely. Is someone with such a strong disbelief/ rejection saved and now with Christ?
