This paper combines organizational and theological frameworks to address the integration of Christian spirituality at work (SAW). It begins with a brief explanation of SAW, followed by a more narrow description of Christian SAW. The paper then provides a snapshot of several integrative models from the SAW literature, after which it offers a new theological model of Christian SAW, noting that Christians want to contribute to God’s new creation while worshipping Him through their work. Both this and the models from the SAW literature are considered to be ‘top-down’ approaches in that they provide guidance for managers on how to integrate employee spirituality. The next section then provides new ‘bottom-up’ qualitative research exploring the underlying conditions that working Christians believe are required for enhancing their spirituality at work. The paper concludes by bringing these two approaches together to produce a new theoretical contribution on how best to integrate Christian SAW, and to achieve the benefits of doing so for an organization.
