In most people's minds "ethnic" or "ethnicity" are terms associated with conflict, cleansing, or even genocide. This book explores-from three perspectives-the significance of ethnic communities beyond these popular conceptions. The first perspective is the reality of the author's own experience as a member of the Welsh ethnic identity. The Welsh are a small people whose whole existence has been overshadowed by the more powerful English. This is the "margin" from which the author speaks. The second perspective is the Bible and evangelical mission and the third is the unprecedented movement and mixing of ethnic identities in our globalizing world. The book ends with the section on ethnicity in the Lausanne Commitment that, hopefully, marks the beginning of serious consideration by the evangelical missions community of this issue that deeply impacts the lives of many millions.
