description of the Martians triggers Peregine's endearing memories of himself launching fire balloons with his grandfather on Independence Day. Peregrine decides to search for and meet Martians, and he and Stone venture into the hills where the prospector encountered them. The two priests are met by a thousand fire balloons. Stone is terrified and wants to return to First City while Peregrine is overwhelmed by their beauty, imagines his grandfather is there with him to admire them, and wants to converse with them, though the fire balloons disappear. The two priests immediately encounter a rock slide, which Stone believes they escaped by chance and Peregrine believes they were saved by Martians. The two argue their disagreement, and during the night while Stone is sleeping, Peregrine tests his faith in his hunch by throwing himself off a high cliff. As he falls, Peregrine is surrounded by blue light and is set safely on the ground. Peregrine tells Stone of the experience but Stone believes Peregrine was dreaming, so Peregrine takes a gun which he fires at himself and the bullets drop at his feet, convincing his assistant. Peregrine uses his authority to have the mission build a church in the hills for the Martians. The church is for outdoor services and is constructed after six days of work. A blue glass sphere is brought as a representation of Jesus for the Martians. On the seventh day, a Sunday, Peregrine holds a service in which he plays an organ and uses his thoughts to summon the Martians. The fire balloons, who call themselves the Old Ones, appear as glorious apparitions to the priests and communicate the story of their creation, their immortality, their normally solitary existences, and their pure virtuousness. They thank the priests for building the church and tell them they are unneeded and ask them to relocate to the towns to cleanse the people there. The fire balloons depart, which fills Peregrine with such overwhelming sadness that he wants to be lifted up like his grandfather did when he was a small child. The priests are convinced and withdraw to First Town along with the blue glass sphere that has started to glow from within. Peregrine and Stone believe the sphere is Jesus.
