Based in France he became a priest in 1776. The French Revolution was a huge turning point in French history. It brought a simple, stable and fruitful way of life to an end for many people. In 1790 there was a civil attempt to turn the clergy into civil servants requiring them to swear an oath of loyalty to the State and its laws. Many refused including Andrew who was removed from his post. Persecution and massacre of bishops, priests and religious began for those who refused to swear to this oath. Andrew continued to minister to his people but his life was in danger and he was sent to Spain for his safety.

After four years he returned and set about restoring peoples lives. Along with a friend Elizabeth he founded the Daughters of the Cross although it is said she preferred to call them the Sisters of St.Andrew. They were dedicated to teaching and looking after the sick, aged and poor. Andrew died on May 13 1834 and was canonised a saint in 1933.
