Pope Francis condemned the prosecution of Christians by Islamic terrorists groups like ISIS and Boko Haram.

The Pope held a mass with a reading from John 16:2-3 where Jesus says “the hour is coming when everyone who kills you will think he is offering worship to God. They will do this because they have not known either the Father or Me.”

Francis said that Christians should take heart when they see people who are killing “Christians in the name of God because they think they are infidels” because Jesus said His followers would be persecuted as He was persecuted.

The Pope cited the murder of 21 Coptic Christians on a beach by ISIS terrorists.

“I called to mind his faithful, who were slaughtered on the beach because they are Christians. Because of the strength given them by the Holy Spirit, they were not scandalized,” he said. “They died with the name of Jesus on their lips. This is the power of the Spirit. Witness. Martyrdom is the supreme witness.”

Vatican police have said that the Islamic terrorist extremists have threatened the Pope’s life.
