Missional ethics is concerned with the way in which the believing community's behaviour is, in and of itself, a witness to the wisdom and goodness of God. The debate surrounding the relationship between word and deed, or evangelism and social action, remains a significant issue within evangelical missiology.

Martin Salter seeks to address one aspect of that debate - namely, the missional significance of ethics - by conducting detailed exegesis of key biblical texts. He argues that biblical ethics is neither entirely separate from, nor merely preparatory for, mission - rather, it is an integral part of the church's mission.

Missional ethics is a theme that arises from the biblical texts and is not imposed on them. The church as both organism and institution embody a missional ethic that includes worship, justice, and charity. Word and deed belong together as an integral whole. Salter's valuable study concludes by offering a definition of missional ethics.
