When Cortes asked for their reply, Ixtlilxochitl burst into tears and answered that he and his brothers understood the mysteries very well. Giving thanks to God that his soul had been illuminated he said that he wished to become a Christian and to serve the emperor. He begged for the crucifix, so that he and his brothers might worship it, and the Spaniards wept with joy to see their devotion.
The princes then asked to be baptized. Cortes and the priest accompanying him said that first they must learn more of the Christian religion, but that persons would be sent to instruct them. Ixtlilxochitl expressed his gratitude, but begged to receive the sacrament at once because he now hated all idolatry and revered the mysteries of the true faith.
Although a few of the Spaniards objected, Cortes decided that lxtlilxochitl should be baptized immediately. Cortes himself served as godfather, and the prince was given the name Hernando, because that was his sponsor's name. His brother Cohuamacotzin was named Pedro because his godfather was Pedro de Alvarado, and Tecocoltzin was named Fernando, with Cortes sponsoring him also. The other Christians became godfathers to the other princes, and the baptisms were performed with the greatest solemnity. If it had been possible, more than twenty thousand persons would have been baptized that very day, and a great number of them did receive the sacrament.
