Pope Leo X beatified Conrad on 12 July 1515 and permitted the town of Noto to celebrate his feast day. On 30 October 1544, Pope Paul III extended permission to the whole island. On 2 June 1625, he was canonized by Cardinal Odoardo Farnese, who was the Duke of Parma and Piacenza in a solemn ceremony at the cathedral of Piacenza, where it was declared an obligatory feast. On 12 September of that same year, permission was granted to the Franciscan Order by Pope Urban VIII for a distinct text for the Divine Office and Mass to be used for his feast; today it is celebrated solely by the Third Order of St. Francis to which he belonged. In Vietnam there is a popular devotion to Conrad.
