There has been an increase in attacks on Christian churches in Egypt since the army took power on 2 July.
These range from graffiti and stone throwing to fire bombs.
Christians make up about 10 percent of Egypt’s 80 million population.
The Muslim Brotherhood has whipped up its sectarian propaganda since Mursi was deposed.
But Revolutionary Socialist Hatem Tallima said, “The Egyptian state has been playing a role in sectarianism. Many suspect it is responsible for some of the attacks so the Brotherhood will take the blame and be denounced as terrorists.
“But it’s also clear the state just hasn’t protected churches when they are under increased likelihood of attack. This leaves them exposed.”
During the 18 days that brought down Mubarak in 2011, Muslims and Christians protected each other at prayer.
