Education, Research, and Publications


Research Interests

  • Generally, I focus my research on the doctrines of God, the Trinity, the Holy Spirit, Pentecostalism, and Karl Barth.

Current Projects

  • Touch of God: The Holy Spirit and Christian Spirituality. I have posted some early excerpts on my blog here and here.
  • Beliefs and Practices of PAOC Clergy: A Study of Attitudes, Beliefs, and Behaviours—Then and Now, with Adam  Stewart. We conducted a survey in October 2014, and we are currently writing a book called Canadian Pentecostal Clergy: Contemporary Trends that assesses the results.
  • Pentecostals and Karl Barth’s Theology, co-editing with Frank Macchia.
  • “The Spirit of Power and Love: Edwards and Pentecostals on Pneumatology,” to be published in From Northampton to Azusa: Pentecostals and the Theology of Jonathan Edwards, edited by Amos Yong and Steven M. Studebaker.
  • “Pentecostals and Karl Barth on (Im)mutability and (Im)passibility.”
  • “The Holy Spirit in the Charismatic Movement,” to be published in The T & T Clark Companion to Pneumatology, edited by Daniel Castelo and Ken Loyer.
  • “A History of the PAOC’s Statement of Fundamental and Essential Truths.”
  • “Spirit Baptism in Early Canadian Pentecostal Theology.”
