In till we have face, what is young Orual’s attitude toward Ungit? The priest? How do think this attitude is likely to evolve as she grows older?

Orual's attitudes toward Ungit and the priest are tempered
by the education she has received from Lysias (the Fox).  As a stoic materialist, the
Fox is unable to attribute to Ungit any power or design that cannot be measured with the
senses.  So, when Ungit behaves in a way that the Fox would determine as illogical, he
determines that in fact the "divine nature" has not behaved illogically, but rather that
the faithful have misinterpreted Ungit or attributed to her things that are impossible. 
He refuses to attribute to the divine nature anything that is mysterious or numinous. 
She begins to see the weaknesses in the Fox's arguments when the priest points out that
it is only illogical that Ungit desires the sacrifice of Psyche as both the Blessed and
the Cursed because the Fox has deemed it so.  However, because the attitude of the Fox
allows her to interfere in the relationship between the God of the Grey Mountain and
Psyche, she clings to the Fox's rationalism even when she has evidence that the Priest's
Ungit is more true.  Eventually, she will understand the weaknesses of rationalism, but
only after she, essentially, deconstructs her whole identity and confronts the lies she
tells herself.
