My heroine's terms of reference is mathematical, my hero's religious.
No theologian or mathemathician I have met provides a model here.
Yet, despite the above declaimers, it must be remembered that just as theologians and mathematicians use impossibilities, such as the square root of minus one or the transubstantiation of wine into blood, to express their eternal verities, so it is with writers and their fictions.
In other words, just because I've made it all up doesn't mean it is not true.
