12 Our demands are not the kind which will diminish the dignity or power of the secular authorities. Rather there may result some substantial and solid advantages for the public welfare. In effect, venerable brothers, what you and your assistants teach concerning civil responsibility comes down to this: every person should be subject to higher powers "not only for fear of punishment, but also because of his conscience."(Rom 13.5) We should bear public duties happily, abstaining from plots and conspiracies. We should show fraternal love to each other and fulfill faithfully our duties to society. If the number of your assistants were to increase, at the same time the number of those who propagate these useful teachings would increase. It would simultaneously become easier to furnish good 'priests to parishes so long deprived of their pastors. Catholics ask this with all their hearts.
