I’d venture to say that it is christian spiritual truth – not spiritual truth in general. It only counts for those who choose to believe in it.
But there aren’t any versions of the truth.
If it’s the truth, it’ the truth for everybody, or else it’s not the truth.
That depends on what you mean by ‘truth’ - I don’t consider it to mean the same thing as ‘fact’ (although there is considerable overlap). Insofar as nobody knows everything about anything, there can be different versions of ‘the truth’ that consist of a subset of elements of ‘The Whole Truth’. [Insert elephant/blind men parable here]
