Extremists vandalised the church with anti-Christian threats translated from Hebrew, "Death to heathen Christians, the heretical enemies of Israel".
The attack on Dormitton Abbey happened on Sunday (16 January) when unknown vandals defaced the walls and doors of the monastery next to the Old City of Jerusalem.
In an interview with charity Aid to the Church in Need, Father Nikodemus Schnabel, subprior of the German-speaking Benedictine community, said: "We are praying for those who hate us. If we are being attacked because we are Christians, then we want to react as Christians."
This is the second attack in less than a month on Christian property in Jerusalem.
Father Schnabel expressed the Jewish community reacted with compassion. He is however concerned. He said: "We ask that the security forces take this criminal act seriously and finally take steps to improve the security situation on Mount Zion, something which has been promised to us since the summer of 2013."
This is not the first time the abbey has been attacked, back in 2013 and 2012 the walls were targeted with graffiti and shortly after Pope Francis visited in 2014, it was nearly set afire.
Jewish extremists have been accused of being behind the attacks.
