Research task. The purpose of this article is to explore the essence of chaplaincy within the All-Ukrainian Union of Churches of Evangelical Christians-Baptists as a form of spiritual and psychosocial support for military personnel, and to examine the theological transformations of Ukrainian Baptism caused by the wartime experience. The main objective is to analyze new ecclesiological orientations, the rethinking of pacifism, the theology of suffering, and the church’s social responsibility. Main material presentation. The article outlines the historical prerequisites for the development of chaplaincy in the Baptist context and analyzes its current practices, which integrate pastoral care, psychological support, and social responsibility. It demonstrates that the war has become a catalyst for rethinking church identity, the role of the faith community in society, and for changing understandings of the theology of suffering, sacrifice, and participation in the struggle for national dignity. The crisis of pacifist ideals, growing support for active Christian engagement, and emerging educational and institutional needs for the advancement of chaplaincy are described. Conclusions. Chaplaincy has become a significant factor in the spiritual mobilization of Ukrainian Baptism during wartime, contributing to theological renewal and the expansion of the church’s ecclesiological vision. It forms a new paradigm of Christian presence in critical social processes and highlights the need for deep theological analysis of war experience and the practical training of ministers. The effective development of this ministry requires institutional support, an interdisciplinary educational approach, and active participation of religious communities in the nation’s recovery.
