Saint is an underling of Bishop Cross, a man of the Vatican who wants to get rich with the technologies unlocked from the Green project. Saint is the one who supervises Kyoji's attempts to understand Green's dna and observers everything for Cross. He also mantains relations with Griffith, who is working directly on cloning Jesus from old blood stains on the Shroud of Turin. In the end he flees after all of the deals go under with the data from the final Green experiment. He seems to be only after money in the end.
