Middle East Concern is highlighting incidences between May and June.
It says individuals have been shot and stabbed, homes have been attacked and a house church stopped from meeting.
In one case a man attacked a nun at a medical centre run by the Coptic Orthodox Church in the town of Biba in Beni Suef province.
The charity says when a guard tried to help the nun he was also attacked. Later the same day the attacker returned, armed with a knife. The guard managed to lock the man out of the centre.
It's reported a complaint was filed with the police, but no action has been taken so far.
Middle East Concern says there are currently four debates in the Egyptian parliament that could have a great impact on Christian communities. These include:
- possible amendments to legislation on blasphemy
- draft legislation to regulate personal status law for Christian communities
- draft legislation to regulate church construction
- two draft bills on equal citizenship for all and countering discrimination (including discrimination on the grounds of religion)
The charity's calling on Christians in the UK to pray that: "The victims of the attacks and their families will experience the comfort and peace of the Lord. That Christian and other communities will be protected from attacks of this kind.
"That the victims will not be forced to take part in 'reconciliation meetings' where they have to forego any right to seek legal redress, and that the authorities will apply the law and prosecute the perpetrators and that the debates in parliament will lead to the adoption of legislation that will grant all Egyptians equality before the law and protection against discrimination on the grounds of religion."
