Edmund was smart, successful, and popular when he gave up his career to become a priest. That was a risky thing to do. Queen Elizabeth had passed laws making it illegal to be a priest in England. He went to France to study for the priesthood. Once he was ordained, he snuck back into England disguised as a merchant. He said Masses in secret and administered the sacraments. Pamphlets were popular at the time and many of them attacked the Catholic faith, St. Edmund wrote one and called it Campion’s Brag. Many people read it because it was encouraging and humorous. It helped the faithful know the truth of their faith and avoid the errors of their time.
