For non-Christians, how did Jesus do it?

[Rodion Romanovich]

I would be interested to hear you explain why that description is different from yours.

doc_bean already answered this, I think

However the idea that this is part of a trend that will continue is a theory (one which I accept), not a fact.

This is the traditional "do we know anything for sure at all" question in philosophy. It depends on how you define "know". The definition of "know" IMO should somehow contain the idea that for something to be known, it must:
1. be true in reality
2. be possible to prove strongly, so that the probability that it is false is low
3. the proof should be reconstructible by others

Depending on how strong our requirement in no. 2 is, we either know some things, or we know nothing at all.

At least we can probably agree that if we don't know anything for sure in science (where statements are usually well supported and immediately rejected when counter-examples are found) then we don't know anything for sure in religion (where statements are unsupported and not rejected when counter-examples are found), according to this definition.
