Red herring
Let's note as well that references to any 'christian' in more than one account before the 4th century were written 'Chrestian' (from Chrestus) which means 'good' or 'useful' ones, then scribes altered the spelling to wipe out the 'e' to replace it with 'i'...to fit into their 'Christian' traditon/theology. (just an interesting note, for what it's worth)
But if you want to play....perhaps one's definition of 'christian' is just as relative or peculiar as one's concepts or images of 'God' are, perhaps?
Note that universal truths and principles of Spirit and Nature are allegorically pictured and archetyped thru myth and metaphor, hence the universal logos and wisdom reveals itself as the golden thread in almost all religious schools and traditions and this is called Theosophy or the
Perennial Wisdom. Hence the 'Christ story' is the mythos of the 'word' becoming flesh, the incarnation of God in Man or as Man
Jesus is the archetype, exemplar and pattern of our own transformation, he being the firstborn among many brethren.
But back on topic, my points made on Josephus hold, and the scholarly debate about the genuineness or forgery of the TF, if you'd like to address that.
