Fr John Bakeni, who coordinates aid for internally displaced people (IDPs) in the Maiduguri Diocese in northern Nigeria, told ACN his concerns.
"The attacks on Christians are growing more flagrant and more aggressive.
"The ongoing conflict with Boko Haram and the attacks by predominantly Islamist Fulani shepherds have instilled a feeling of great uncertainty and fear in us Nigerians.
"We consider each day we live in safety a blessing, because we do not know what will happen the next day."
Fr Bakeni added that it was "difficult to be a Christian in this part of the world, but our faith encourages us to bravely bear witness to the Gospel".
He also criticised the Nigerian government's efforts to stop the attacks by extremist groups.
"The state is not putting forth much effort when it comes to the protection and safety of the lives and property of Christians," he said.
"We citizens, no matter whether we are Christians or Muslims, expect the state to protect us and ensure our safety."
Boko Haram, the ISIS-aligned terrorist militia, has been waging a campaign in the West African region, murdering Christians, kidnapping young girls, and burning villages to the ground for more than a decade.
The number of its victims now stands in the tens of thousands since 2009.
