The Pew Research Center numbers Christians in the Arabian Peninsula at 2.3 million—more Christians than nearly 100 countries can claim. The Gulf Christian Fellowship, an umbrella group, estimates 3.5 million. These migrants bring the UAE’s Christian population to 13 percent. Among other Gulf states, Bahrain, Kuwait, and Qatar are each about 14 percent Christian, while Oman is about 6 percent. Even Saudi Arabia, home to Islam’s holiest cities (Mecca and Medina), is 4 percent Christian when migrants are counted.
