Report: Christianity in Iran growing faster than anywhere else in the world

According to forecasts, by 2050 the number of Christians in Iran may increase by 1.5–2.2 times, despite the ongoing pressure from the state.
Despite severe restrictions and systematic persecution by the authorities, Christianity is rapidly spreading in Iran. According to the international human rights organization International Christian Concern, Christianity in Iran is growing faster today than anywhere else in the world.
According to information from the Christian mission Open Doors, in 2014 the number of Christians in Iran was about 370,000 (approximately 0.5% of the population). However, by 2025, according to the organization Article 18, this number has nearly doubled to reach 800,000.
Experts attribute this dynamic to the disillusionment of part of Iranian society, especially the youth, with the official state ideology – Shia Islam. Against the backdrop of perceiving Islamic doctrine as harsh and repressive, evangelical Christianity attracts with its openness, emphasis on personal faith, and vibrant communal relationships.
The increase in conversions to Christianity raises concerns among the Iranian leadership, which sees this as a manifestation of "foreign influence" and a threat to national security.
Despite the fact that the Constitution of Iran recognizes Christianity as a minority religion, conversion from Islam to another faith remains a criminal offense, punishable by death.
As reported by Article 18, in 2022, 134 Christians were arrested in Iran for practicing their faith, at least 30 of whom received prison sentences or were forced to leave the country.
By the end of 2022, at least 17 Christians continued to serve prison sentences of up to 10 years on charges of "propaganda against the regime" and "threat to national security."
According to forecasts by the Pew Research Center, by 2050 the number of Christians in Iran could increase by 1.5–2.2 times, despite ongoing pressure from the state.
Earlier, the UOJ reported that two Christians were re-arrested in Iran for participating in home services.
