Today, a large section of the global Christian population is located in Africa, Latin America, and Asia. This encyclopaedia documents the historic presence and contributions of Christianity in India and its neighbouring South Asian countries (Bangladesh, Bhutan, Nepal, Pakistan, Sri Lanka, and the Maldives). In addition, the volume includes entries on Afghanistan and Myanmar and on the global South Asian diaspora.

Looking at rich archival material, the work documents the extensive apostolic heritage and the growth of the indigenous church in the post-colonial era, including that of the recent upsurge of the Christianity in some regions (for example, in North-East India and in Nepal), and a proliferation of churches of indigenous origin. Broadly covering events, people, institutions, concepts, theological issues, churches, denominations, historical developments, and contemporary themes, the topics have
been addressed keeping in view the South Asian context, its nuances and distinctiveness.

An essay on each country opens a window to the history, particularly the Christian component of that country from the beginning up to the present time. In the case of India, there are essays on regions alongside essays on each of the states and several important cities. Orthodox, Catholic, Protestant, and Indigenous Independent (including Pentecostal) traditions have been covered. Separate articles feature major denominations and important institutions and agencies in the region, particularly
those of historical significance. Additionally, a number of themes and topics have been addressed which show the contributions of Christians from South Asia to various aspects of theology, ecclesiology, missiology, ecumenics, sociology, nation-building, politics, economics, culture, religion, and
society. For easy reference, the contents are arranged alphabetically. Cross-references and brief bibliographical entries help scholars for future research. The bibliographies that most articles conclude with offer an invitation to further exploration.
