We are aware of a blog entitled 'Church of England's Synod may abolish Holy Trinity to include Muslims'.
Apparently some commentators appear not to have realised the author intended it to be a joke. For the avoidance of doubt, this article is entirely without basis of fact, and is published marked as 'satire'.
The agenda for the July 2018 General Synod can be found here, including details of all Private Member Motions listed for debate.
The Church of England remains fully committed to the doctrine of the Trinity.
