And when he was twelve years old, he fasted forty days and forty nights, the fast of our Lord. He began to fast all the fasts of our Lady Mary, who gave birth to God, and all the fasts of the apostles. His father and mother rejoiced when they saw him fast all the fasts at the age of twelve. They did not know that this child of theirs was strengthened by the grace of the Holy Spirit.
