An apocryphal New Testament book, specifically one of the infancy Gospels.
A dominant theme is sexual abstinence, reflecting Platonic ideas which disparage the physical body.
The Gospel of Thomas has an account of 5-year-old Jesus accused of breaking the Sabbath by making sparrows of clay beside a stream. When Joseph investigates, Jesus claps his hands, and the clay birds come to life and fly away chirping.
Another time, Jesus appeared in the form of Thomas, exhorting a newly married couple to dedicate themselves to virginity.
