6 It remains, therefore, for you, Venerable Brethren, to set yourselves to work and to employ all means which the law recognizes as within the rights of all citizens to arrange for and organize religious worship. In a matter so important and so arduous you will never have to wait for Our assistance. Absent in body, We shall be with you in thought and in heart, and We shall aid you on every occasion with Our counsel and with Our authority. Take up with courage the burden We impose upon you under the inspiration of Our love for the Church and for your country, and entrust the result to the all-foreseeing goodness of God, Whose help, We are firmly convinced, will not, in His own good time, be wanting to France.
