Religion in Greece is dominated by Christianity, in particular the Greek Orthodox Church, which is within the larger communion of the Eastern Orthodox Church. It represented 90% of the total population in 2015[1] and is constitutionally recognized as the "prevailing religion" of Greece. Religions with smaller numbers of followers include Islam (comprising 2%[1] of the population), Western Catholicism (comprising 1%[1] of the population), Greek Catholicism, Judaism, Evangelicalism, Hellenic paganism, and Jehovah's Witnesses. A small number of Greek atheists exist, not self-identifying as religious.
Religion is key part of identity for most Greeks, with 76% of Greeks in a 2015–2017 survey saying that their nationality is defined by Christianity.[2] According to other sources, 81.4% of Greeks identify as Orthodox Christians and 14.7% are atheists.[3]
