9 It rejoices Us to think that each of you will become a confluence of the charity and generosity flowing in from your faithful children, and that you will become also the centres from which the alms offered to you will be distributed. In dioceses where this will be more convenient We see no objection to your joining forces with your respective Metropolitans, or even with some charitable organization which has given proof of its efficiency and enjoys your confidence.
