By 1790, the anticlerical Terror phase of the French Revolution forced many loyal priests to hide from the regime in order to carry out the sacraments in their parish. Even though to do so had been declared illegal, the Vianneys traveled to distant farms to attend Masses celebrated by priests on the run. Realizing that such priests risked their lives day by day, Vianney began to look upon them as heroes. He received his First Communion catechism instructions in a private home by two nuns whose communities had been dissolved during the Revolution. He made his First Communion at the age of 13 in a neighbor's kitchen; during the Mass, the windows were covered so that the light of the candles could not be seen from the outside. His practice of the faith continued in secret, especially during his preparation for confirmation.
