I insist that each one takes a rest of fifteen days between one mission and another.
Letter to Pierre Mie, 3 December 1824, quoted by Rey I page 340
The zeal of the young Missionaries had to be nurtured. On the parish missions, which lasted around 6 weeks, they burnt themselves out from early morning till late at night to ensure the best service to the people. Totally exhausted at the end of the mission, they were ready to throw themselves enthusiastically into the next one. Eugene knew, from his personal experience, how damaging this was to their health in the long-run, so he insisted on a period of rest. What it meant was that they would come back to the community and participate fully in its life and the pastoral activities of the group. It was not a holiday but a change to activity to something not as highly-pressured as a parish mission.
