The Church Council of Laodicea circa 364 CE ordered that religious observances were to be conducted on Sunday, not Saturday. Sunday became the new Sabbath. They ruled: "Christians shall not Judaize and be idle on Saturday, but shall work on that day." There are many indicators in the historical record that some Christians ignored the Church's ruling. Sabbath observance was noted in Wales as late as 1115 CE. Francis Xavier was concerned about Sabbath worship in Goa, India in 1560 CE; he called for the Inquisition to set up an office there to stamp out what he called "Jewish wickedness". A Catholic Provincial Council suppressed the practice in Norway in 1435 CE.
