It is worth reading the two letters that have been published with this joint statement.
There are helpful reminders and clarifications in the letter from Alison Tomlin (President of the Methodist Church in Great Britain) such as the resolution passed in 1983 (that is still valid today):
“The Conference records its distress in recent times of antisemitic actions against the homes and places of worship of Jewish people in Britain and elsewhere, notably Western Europe and the Soviet Union. It confesses that Christian history and belief have been gravely disfigured by sinful prejudice against Jews and urged Methodists and local Methodist churches to resist and condemn expressions of antisemitism, and encourage relations of love, respect and dialogue with Judaism and Jewish people.”
It is good to see that despite some of the rhetoric that floats around the internet that behind the scenes progress has been made.
