The head of the Scottish Episcopal Church says it is "deeply distressed" by the offence caused by a reading of the Koran at a Glasgow cathedral.

A verse from the Islamic holy book asserting that Jesus is not the son of God was recited at St Mary's Cathedral, sparking condemnation from Christian groups.

Police are investigating online abuse directed at members of the church following the reading at Christmas.

Primus Bishop David Chillingworth said the church has had a "long commitment to the development of interfaith work".

"The decisions which have led to the situation in St Mary's Cathedral are a matter for the provost and the cathedral community," he said.

"But the Scottish Episcopal Church is deeply distressed at the widespread offence which has been caused. We also deeply regret the widespread abuse which has been received by the cathedral community.

"In response to what has happened at the cathedral, the Scottish Episcopal Church will bring together all those who are involved in the development of interfaith relations.

"Our intention will be as a church to explore how, particularly in the area of worship, this work can be carried forward in ways which will command respect.

"Our desire is that this should be a worthy expression of the reconciliation to which all Christians are called."

The Koran was read at the Kelvinbridge cathedral after members of Glasgow's Muslim community were invited to join epiphany celebrations at the church.

A video of the reading was posted on YouTube and later removed.

A statement from St Mary's said: "St Mary's has received a number of offensive messages on Facebook and other platforms.

"These have been reported to Police Scotland. We are grateful to the police for their support at this time."
