The update to the penal code in February 2021 suggests that religious freedom in Iran will continue to be severely restricted.
Three Iranian Christian converts have had their sentences reduced from five years to three years.
Iran already increased the criminalisation of Christian activity with updates to the Penal Code this year.
Last year, Christian convert Fatemeh Mohammadi was arrested during an anti-government protest in Tehran.
It is widely believed that this new law will serve as a more precise or expanded tool to suppress religious freedom.
The Christian man was sentenced to death because of his faith, but he continued to pray in the prison, and God saved his life.
Iranian Christians often are forced to sign agreements to abstain from gathering at house churches.
The Iranian government has not intervened or indicated that they seek to seek to preserve the Christian minority sites.
