105 We also extend Our paternal best wishes to Our sons in religious orders and congregations. These men have embraced the various states of evangelical perfection and live according to particular rules of their Institutes in obedience to their superiors. We urge them to strive tirelessly and with all their strength for the achievement of the goals their founders have set forth in those rules. They should, in particular, be fervent in prayer and assiduous in works of penance; they should undertake the sound formation and education of the young and assist, so far as they can, those who are beset in any way by want or distress.
