Bizarre though it may be, the words of the Polish chief rabbi about the attitudes of a Polish MEP have become crucial to the debate about the future of Britain, to its relationship with Europe and, perhaps, to the future of the foreign secretary.
David Miliband had passionately attacked the Tories' new European allies and, in particular, the leader of their new grouping in the European parliament, Michal Kaminski MEP - who Miliband described as "a man denounced by the chief rabbi of Poland for an anti-Semitic, neo-Nazi past" as a former member of the extremist Polish Revival Party (NOP) - and as an opponent to this day of a national apology for the massacre of Jews by Poles in 1941.
Miliband quoted Poland's chief rabbi, Michael Schudrich in the New Statesman:
"I do not comment on political decisions. However, it is clear that Mr Kaminski was a member of NOP, a group that is openly far right and neo-nazi. Anyone who would want to align himself with a person who was an active member of NOP and the Committee to Defend the Good Name of Jedwabne (which was established to deny historical facts of the massacre at Jedwabne) needs to understand with what and by whom he is being represented"
However, this morning the chief rabbi has made it clear on the Today programme that, though he will not forget or condone Mr Kaminski's past, he regards the MEP today as an opponent of anti-Semitism, a friend of Israel and a member of a mainstream political party.
This will fuel William Hague's demand for an apology from Mr Miliband.
It won't, I suspect, be forthcoming. The foreign secretary could argue that no-one disputes Mr Kaminski's past - something he feels particularly passionate about given his own family's Jewish roots.
What's more, David Miliband knows that this controversy has highlighted the Tories' European stance when all previous attempts to do so have failed. He also knows that his attacks have unnerved some in the Jewish community who were thinking of backing the Tories just as his attacks on the alleged homophobia of other Tory allies has been used to try to win back the gay vote for Labour.
However, for the first time in this controversy, the Tories feel they are on the front foot. They will argue that alleging extremism in the leader of a foreign political party even after the chief rabbi of that country has exonerated him is not fitting behaviour for a foreign secretary.
And with Tony Blair's presidential hopes fading, it may not help those who hope that Mr Miliband will switch from being Britain's foreign secretary to being what many will regard as Europe's - the new High Representative role which will come into being if and when the Lisbon Treaty becomes law.
PS: Labour MP Denis MacShane has indeed claimed that this morning's interview changes nothing and that the chief rabbi "does not clear Kaminski", adding: "until Mr Kaminski expresses full and unreserved regret over what he said and did in relation to the Jedwabne massacres I will continue to criticise the Tory alliance with him."
