3 What must be thought of the conditions imposed by the government of Portugal on religious families if they are to survive, you have already eminently declared. This must be kept in mind throughout, however, that in accord with the discipline of the Catholic Church, no religious order can exist or prosper if its novitiate and vows are removed. Therefore the laws proper to each Institute, if perhaps necessary, are to be brought into conformity with civil prescriptions; but this must only be done in such a way that the dignity of the individual religious be preserved and, most importantly, that the nature of their holy state be kept entire and intact.
