Christianity in Kuwait

Christianity in Kuwait is a minority religion, accounting for 18%-20% of the country's population, or 650,000 - 750,000 people. Kuwait's Christians can be divided into 2 groups. The first group are Christians who are native Kuwaitis numbering approximately between 200 and 400 people. The second group, who make up the majority of Christians in Kuwait, are expatriates from various countries around the world. 
There are also a number of believers in Christ from a Muslim background in the country, though many are not citizens. A 2015 study estimates some 350 such Christians in the country that are ex-Muslim.
Kuwaiti Christians.
Kuwait's native Christian population is diverse. There are between 259 and 400 Christian Kuwaiti citizens. In 2014, there were 259 Christian Kuwaitis residing in Kuwait. Latest estimates in December 2019 put the community at 290 with the slight increase most likely a result of a return of a few Kuwaiti Christian emigrants.
Christian Kuwaitis can be divided into two groups. The first group includes the earliest, who were Iraqi Christian (Assyrian/Chaldean) and Turkish Christian (Antiochian Greek) immigrants and their local-born descendants. They have assimilated into Kuwaiti society, like their Muslim counterparts, and tend to speak Arabic with a Kuwaiti dialect; their food and culture are also predominantly Kuwaiti. The make up less than a quarter of Kuwait's Christian population. The rest (roughly three-quarters) of Christian Kuwaitis make up the second group. They are more recent arrivals in the 1950s and 1960s, mostly Kuwaitis of Palestinian ancestry who were forced out of Palestine after 1948. There are also smaller numbers who originally hail from Syria and Lebanon. This second group is not as assimilated as the first group, as their food, culture, and Arabic dialect still retain a Levant feel. However, they are just as patriotic as the former group, and tend to be proud of their adopted homeland, with many serving in the army, police, civil, and foreign service. Most of Kuwait's citizen Christians belong to 12 large families, with the Shammas (from Turkey) and the Shuhaibar (from Palestine) families being some of the more prominent ones.
Although there is a small community of Christian citizens, a law passed in 1981 prevents the naturalization of non-Muslims. However, male citizens who were Christians before 1980 (and male children born to families of such citizens since that date), can transmit their citizenship to their children; however, they cannot transmit their citizenship to their spouses.
Kuwait is the only GCC country besides Bahrain to have a local Christian population who hold citizenship.
Traditionally, Eastern Orthodox Christians in Kuwait belong to the jurisdiction of Eastern Orthodox Patriarchate of Antioch and All the East. Eastern Orthodox parish in Kuwait was reorganized in 1969 by late metropolitan Constantine Papastephanou of Baghdad and Kuwait (1969-2014), who visited Kuwait on many occasions. His successor is Metropolitan Ghattas Hazim of Baghdad and Kuwait (since 2014). His official seat remains in Baghdad, but administrative headquarters of the Archdiocese are located in Kuwait. Today, Eastern Orthodox parishes in Kuwait are administered by priests Ephrem Toumi and Filimon Saifi.
