We read about one of the first changes St Philip introduced to his work with laymen in Rome. He built an oratory, a little house of prayer, at his own expense. Until that time, he was receiving a group of men in his room at San Girolamo to explain the Word of God to them. But once they decided to go to India and then changed their minds, new crowds of men were gathering around St Philip. He had to do something. His room was not big enough. He built something simple, but larger.
