The emergence of the concept of Missio Dei (Mission of God) from the perspective of the International Missionary Council (IMC) arguably demonstrated that the role of the Triune God in his own mission was undeservedly marginalized for decades, if not centuries preceding 1952. Over the past decades there has been a sustained research activity conceptualizing Missio Dei, and at the same time renewing missiological interest in other Christian missions. However, to the author’s awareness, there has been very little or no effort to introduce or use known project models that can be utilized to show coherence or collaboration of missions towards the project of fulfilling the objective of Missio Dei. Through a desk-top literature review, this paper proposes the use of a project management model to properly conceptualize the location of Missio Dei as a main project that includes other network of missions as sub-projects within its framework. The Triune God is here identified as Project managers while human participants are seen as project stakeholders. Christian missions include Missio Christos, Missio Spiritus, Missio Hominum and Missio Ecclesiae as sub-projects. The proposed model will demonstrate the coordination and collaboration of missions in the broader context of Missio Dei and further assist with a proper understanding of roles that each mission is, or should play, in achieving the objective of Missio Dei. While efforts are being made here to propose a project management model for Missio Dei, further research is needed to determine whether this proposal will yield an in-depth understanding of Missio Dei as a missiological paradigm in conjunction with the role of other missions.
