Several articles in the Bulletin des gardes-malades catholiques and the Bulletin des infirmières catholiques du Canada refer to the personalist philosophy. In this article, we posit that this philosophy influenced the "social sense" promoted by the Church among nurses from 1934 to 1959 and that it enabled the transfer from a charitable model to one challenging the social order. We present the Bulletins as agents of resistance to a science perceived as being devoid of morality, in the face of a growing administrative technocracy seen as detrimental to human beings' living conditions. These sources allow us to give a different interpretation to nurses' contribution to the modernization of care given to the poorest families. We contend that it is beyond institutions and inspired by personalim that French-speaking Catholic nurses laid the groundwork for community health in Canada.
