Background: Pentecostalism in the Evangelical Lutheran Church in Southern Africa (ELCSA) is profoundly believed, strong and alive. In ELCSA, the Holy Spirit is affirmed and gives power to believers as the gracious gift that sustains and enables the very church to perform its duties of worshipping God, healing, preaching and meeting other spiritual needs. The Holy Spirit is actively acknowledged and worshipped as a gracious Spirit. Aim: The objective of this current study is to reflect on the scope of the work of the Holy Spirit in the ELCSA. Setting: The article discusses the role of the Holy Spirit within a context of the Evangelical Lutheran Church in Southern Africa. Methods: A collection of secondary sources such as books and journals, and primary data such as unpublished papers, minutes and other documents are analysed within a qualitative method. Results: Findings of the study include the fact that the ELCSA traces its practices of Pentecostalism from scripture and sacraments. Circuit Easter conferences and revivals attracted people for ELCSA membership growth. Conclusion: The Holy Spirit has entrusted the Evangelical Lutheran Church to contribute to the Pentecostalism phenomenon. Contribution: The study contributes to how the ELCSA had an impact in Christianity by embracing the Holy Spirit and Pentecostalism. Some basic topics of the doctrine of Pneumatology are discussed in relation to the ecumenical creeds and Book of Concord.
