The Centre for Biblical Preaching 

Our mission  at the Centre for Biblical Preaching is to encourage and foster expository preaching and teaching in local churches throughout Melbourne, Australia, and in other countries, by providing workshops, conferences, seminars, and mentoring for preachers.

We strive to be a training centre that effectively equips churches throughout Australia and the rest of the world in expository preaching. This vision is founded on the conviction that the first and most important mark of a healthy church is faithful exposition of God’s word.

The Centre arose from the unique and ground–breaking partnership between St. James’ Old Cathedral in West Melbourne and the Church Missionary Society—Australia.
