| Across the 19th century Arab East, or Mashriq, there were two simultaneous but seemingly contradictory trends afoot. On the one hand, new ways of understanding religion, science, and community, often associated with the intellectual 'revival' of the Arab Nahda, ushered in new forms of thought and more fluid subjectivities. On the other hand, movements emerged to reinscribe, intensify, and uphold stricter communal boundaries between religious groups. How did these two trends coexist? The life and thought of Mikha'il Mishaqa (1800-1888) offer some answers. Mishaqa was a doctor, merchant, moneylender, and writer who was raised in Greek Catholicism, lost his faith, regained it, and then converted to Protestantism. Through his many-sided life, his voluminous writings, and his obstinate commitment to 'reason', Mishaqa offers an example of how a single life could integrate these seemingly contradictory trends of 19th century Arab East.
