Daniel went down and eventually found Isaac bent and kneeling in the chapel, wracked with agony, praying desperately for the salvation of his immortal soul. Daniel could not but sympathize, though he knew too little of sin and too little of Isaac to guess what his friend might be repenting for. Daniel sat nearby and did a little praying of his own. In time, the pain and fear seemed to ebb away. The chapel filled up. A service was begun. They took out the Books of Common Prayer and turned to the page for Whitsunday. The priest intoned: 'What is required of them who come to the Lord's Supper?' They answered, 'To examine themselves whether they repent of their former sins, steadfastly purporting to lead a new life.' Daniel watched Isaac's face as he spoke this catechism and saw in it the same fervor that always lit up Drake's mangled countenance when he really thought he was on to something. Both of them took communion. This is the Lamb of God who takes away the sins of the world .
