Four Iranian Christians will soon begin serving ten-year prison sentences after a court ruled the Church of Iran members were “promoting Zionist Christianity” and running house churches.

A court recently upheld the convictions sending the four men to prison for longer than was expected, and they could receive a call within the next day to report at the prison gate in their home city of Rasht, according to World Watch Monitor.

Among the group is Youcef Nadarkhani, a pastor who has been arrested several times by the Iranian government. In 2010 he was sentenced to death on charges of apostasy. He was acquitted two years later but arrested again and detained briefly in 2013.

Nadarkhani and fellow church members – Mohammad Reza Omidi, Mohammad Ali Mosibzadeh, and Zaman Fadaei – were arrested in 2016 ” while performing Christian rituals at the house of a friend.”

The most recent annual report of the United States Commission on International Religious Freedom (USCIRF) lists Iran as a “country of particular concern” for engaging in “particularly severe religious freedom violations.” The report estimates there are approximately 300,000 Christians in Iran. Christians suffer various forms of persecution, including surveillance, restrictions on church construction, and arrests.

The USCIRF’s assessment is echoed by the State Department’s 2017 Annual Report on International Religious Freedom, which states Christians in Iran have “continued to experience disproportionate levels of arrests and detention” over the past year. United States Ambassador-at-Large for International Religious Freedom Sam Brownback spoke upon the release of the annual report last week, and he referred to reports of religious freedom violations in Iran as “horrific.”
