Endogamy and Religious Boundaries in a Transnational Context—The Case of Knanaya Christians in North America

The Knanaya Christians, also referred to as Thekkumbhagar or Southists, represent a distinct endogamous group within the wider community of Saint Thomas Christians of southern India. Their origins can be traced to the arrival of Jewish Christians led by Knai Thoma or Thomas of Cana, who migrated to the Malabar Coast from Persia in 345CE. Upon their arrival, they mingled with the established Christian population of the Malabar Coast, known as the Vadakkumbhagar or the Northists, whose roots extend back to the apostolic mission of Saint Thomas in the 1st century CE. However, the Knanaya Christians have successfully preserved their unique identity through the practice of endogamy, which keeps their bloodlines separate from those of the Vadakkumbhagar, while also maintaining a spiritual connection and liturgical continuity with the latter. Despite their matrimonial exclusivity, the Knanaya Christians have followed the same developmental path as the larger Thomas Christian community, sharing liturgical practices, enjoying similar privileges, facing the same challenges during the Portuguese era, experiencing divisions in the 17th century, and striving to preserve their identity. The migration of this endogamous community to other parts of the world since the mid-20th century, in similar lines with different groups of Thomas Christians, has posed challenges to their traditions and practices, especially endogamy. This paper explores how Knanaya Christians maintain and adapt their endogamous marriage traditions in transnational settings by focusing on how Knanaya religious authorities and lay members collectively negotiate these tensions—whether by reinforcing endogamy or adapting it in response to shifting realities in North American settings.
