churches in Houston: St. Mark Coptic Orthodox Church in Bellaire, the St. Mary and Archangel Michael Church in northwest Harris County, and the Archangel Raphael Coptic Orthodox Church in Clear Lake City. The St. Mary and Archangel Michael church began church services on July 25, 2004, had 200 families in August of that year, and was built at a cost of $2.5 million. The St. Mary and Archangel Michael church is the largest Copt church in the Houston area. In the late 1960s there were far fewer Coptic families. They were served by a priest from Los Angeles, who would fly monthly to Houston and hold mass in a borrowed Orthodox church or in a private house. From 1968 to 2006, more than 600 Coptic families moved to Houston. Due to sectarian strife against Copts in Egypt, by 2006 the number of immigrants had increased and membership of Copt churches in Houston was growing. In 2006 Gregory Katz of the Houston Chronicle said that, partly because many Copt church leaders are accustomed to anti-Copt attitudes in Egypt, those who come to Houston are not accustomed to speaking freely about their religious beliefs. They "do not mingle easily with the rest of the large Christian community in the Houston area". After the 2011 Alexandria bombing in Egypt, Houston Coptic churches cancelled their Coptic Christmas services. Parsis The Parsi in 2000 made up one of the two chief ethnic groups practicing the Zoroastrian religion. As of that year the total number of Iranians of all religions in Houston was larger than the total Parsi population by a ratio of 10 to 1. As of 2000 the members of the Zoroastrian Association of Houston (ZAH) are majority Parsi. Rustomji wrote that because of that and the historic tensions between the Parsi and Iranian groups, many Iranians in Houston did not become full members of the ZAH. Rustomji said that Iranian Zoroastrians "attend religious functions sporadically and remain tentative about their ability to fully integrate, culturally and religiously, with Parsis." Sikhs In 2012 the Sikh National Center stated that the city of Houston has 7,000 to 10,000 Sikhs. The Gurdwara Guru Teg Bahadur Sahib Ji is a Sikh temple in Houston, located off of Fairbanks North Houston. As of 2012 the majority of the city's Sikhs originate from the portion of Punjab in India.
