Meanwhile, in England there was considerable uncertainty among the faithful as to how far it was lawful to conform outwardly with the State religion. Pius V commissioned two of the exiles at Louvain, Doctors Sanders and Harding, to publish his decision, informing the Catholics that to frequent the Established services was a mortal sin. Vaux was in Rome in 1566; in a private audience the pope instructed him more fully as to the scope of his decision, and finally the task of making known the papal sentence in England was delegated to him. He returned therefore and conducted a vigorous and successful campaign against the schismatical practice, especially in his native Lancashire. This activity drew down the anger of the Government on his head, and in February 1568, a queen's writ was issued for his arrest; this document mentions also Cardinal Allen, though he was not in the country at the time. Vaux again escaped and returned to Louvain.
