The Church of England policy is official UK policy per their being part of the govt.
Seriously you have no idea what you're talking about.
A)The Queen doesn't make the administrative decisions for the Church
B)The goverment doesn't fund the Church.
C)Because a goverment entity i.e. San Fransico decides to be against the war, does not mean the US policy is to be against the war. Same thing here. Simply because the Church decides to 'divest' from Israel, does not make it official UK policy to 'divest' from Israel.
It really looks like your'e stretching for reasons to bash Sean, by painting him as hyppocrite.
