This article maps the theology of Christo van der Merwe as a mobilising
theology which aided the Netherdutch Reformed Church in Africa (NRCA) in discerning its
character, role and purpose. The core of Van der Merwe’s theology consists of a journey with
God as encountered in the narratives about Jesus and the Spirit told in the Christian Bible. The
article shows that the mobilising core of his theology is due to an ‘interoperational relationship’
between ‘knowing and believing’. In the article, the metaphor ‘roaming’ is used to illustrate
this biographical journey as contextual theology which equips pastors with ministerial skills
to take care of people who are haunted by trauma.
