Analyse the character of the whiskey priest.how does the change over the course of the novel? What motives his action and decisions

The protagonist of The Power and the Glory is an unnamed priest who lives and preaches in Mexico during a period in which the Mexican government outlawed Catholicism and heavily suppressed the religious practice. The plot follows him as he travels across the state of Tobasco to avoid capture, and murder at the hands of the Lieutenant. He is a very vane man, seeking dignity and esteem instead of holiness. It is revealed that the priest is unchaste, as he drinks heavily. Contravening the priestly vow of celibacy, he also fathered a daughter, Brigitta, with a woman named Maria. Despite this, he still preaches and practices his faith, though with a heavy sense of guilt. While travelling to Carmen, he undergoes a spiritual renewal mirroring that of Christ in the desert. As he moves with haste to perform the last rites of a dying man, he is captured by the state and executed.
