42 We know that the congregations of sisters in Portugal are growing every day. Among them therefore let a diligent and careful choice be made of those who are called to the aid of the missions. In such a manner they may set out daily - in greater numbers and better trained - to enter upon their tasks as nurses of the sick, teachers of children, mistresses of catechetics, and able to perform all the tasks which their special apostolic duties demand.
