Many first generation immigrants share a concern for retaining their heritage culture, though they still aspire to successfully assimilate into the country of residence society. Assimilation theories suggest facilitating factors for positive assimilation but differ in terms of whether the loss of heritage culture is inevitable. The Coptic diaspora illustrates that upward mobility can be achieved without loss of heritage identity. Religious structures can play an important role not only in sustaining heritage identity but also facilitating positive assimilation. A review of the Coptic Orthodox Church’s ministry in diaspora, along with findings of a Coptic diaspora survey may offer lessons for other immigrant groups. The study affirms some theoretical findings and raises questions for future research.
