Dennis Ackermann’s feminist theology of praxis was forged in lament. Steeped in the dehumanising apartheid system, she wrestled with collective and personal experiences of suffering, pain, and trauma. A review of her background demonstrates her practice as an engaged activist scholar who grounded her understanding of lament as an ancient practice, replete in the Hebrew Scriptures. Her depth of understanding of lament is brought to bear on her reflections of the South African Truth and Reconciliation Commission and her links to a protest movement known as, The Black Sash, highlighting the context of the marginalized and traumatized. Her weighty deliberations about the loss of lament reveal significant theological, liturgical, pastoral, and political implications for the faith community. Calling for public lament, Ackermann’s insights prove instructive today for the faith community to engage in matters of justice in society
