ISCAST’s fifteenth biennial Conference on Science and Christianity will be held in Melbourne from 6 to 8 November 2026.
Scholars have long debated how science and faith meet. Some see them as fundamentally unintelligible to one another. Others see a deeply fruitful partnership where different approaches offer complementary insights into the nature of reality.
Today, new thinking is breathing fresh life into the field. Movements like “science-engaged theology” and work described as “after science and religion” are renewing the conversation, re-examining old assumptions to connect rigorous scholarship with the lived experiences of churches, professionals, and the wider community.
Whether you are a scholar, a church leader, an educator, or a curious layperson, COSAC 2026 invites you to reflect on enduring questions:
- How does our faith inform our understanding of the natural world?
- How can scientific discovery enrich the life of the church?
- In a fractured world, how can we foster a dialogue that is intellectually serious, pastorally attentive, and publicly engaged?
Program
The full conference program is now available, with more than thirty papers. This year’s keynote speakers are:
- Professor Peter Harrison (Some New World: Myths of Supernatural Belief in a Secular Age)
- Dr Nicola Hoggard Creegan (Animal Suffering and the Problem of Evil)
- Dr Nick Spencer (Magisteria: The Entangled Histories of Science and Religion)
- Dr Paul Tyson (A Christian Theology of Science)
Attend
You can attend in person at Catholic Theological College in East Melbourne, or join the Saturday and Sunday sessions online from anywhere. The conference opens with an in-person public lecture in the Melbourne CBD by Nick Spencer and Peter Harrison on Friday 6 November.
