"There have always been Jєωs that have converted (to the Catholic faith) and if they have really converted, they make magnificent Catholics. Because as St. Paul says in the Epistle to the Romans, the religion of God is in their bloodstreams. And when a Jєω truly rediscovers the Catholic Faith, He's coming home in a way that no gentile is coming home. He's coming back to Our Lord, and the Apostles and Our Lady who were all Jєωιѕн. The Catholic faith was founded by Jєωs. And when Jєωs come back to it, they're coming home. ... A gentile can never be at home in the Catholic faith in the same way that a real Jєωιѕн convert can be."

Anti-Semitism means many things today, for instance, when one criticizes the Israeli actions in the Gaza Strip. The Church has always understood the definition of anti-Semitism to be the rejection of Jєωs because of their Jєωιѕн roots. This is condemned by the Church. Incidentally, this is self-evident in a religion whose founders and all important individuals in its early history were Jєωs. But it was also clear, because of the large number of Jєωιѕн Christians in early Christianity, that all men need Christ for their salvation -- all men, including the Jєωs.

I have been trying to research this topic and finding it quite frustrating.  The vast majority of search results are too inaccurate and hostile to be of any use and there are so many of them that they bury what would be useful.

I have a couple of specific questions, but am also interested in related information.  I have found this quote on Cathinfo:
This is attributed to "Bishop Williamson 2003" with no further information about its source.  I would like to see it in context (or if he even said it at all - I have my doubts about it).  Does anyone know where it came from or have suggestions how I can find out?

I am also interested in seeing him expand on this comment from his 2009 Der Spiegel interview, especially the part I have bolded:

I am looking more for his theological perspective on Jєωs in general rather than his specific views on the "h0Ɩ0cαųst" narrative which I am already familiar with.

Thanks for any help you can provide.

For what purpose are you doing research on +W's theological perspective (in general) on Jєωs?  

I consider him a good source for learning about the traditional Catholic view.  More specifically I am wondering about the morality of continually claiming that a Catholic convert from Judaism is not a genuine convert, in spite of the lack of evidence for this claim.  But, to understand that question, I want a better grasp of traditional teaching on Jєωs in general to give me the necessary context.

Historically, Catholics did not consider this as a private matter.  There was period when there were a lot of false conversions and this was considered a serious problem.  One of the roles of the Inquisition was to investigate accusations of false conversions.  In theory, this allowed trained, impartial experts deal with the matter rather than leave it to mobs or personal vendettas.  

I think this shows the serious and public nature of false conversions, but it was such a different situation from our own that it hard to see exactly how applies to us.

This is attributed to "Bishop Williamson 2003" with no further information about its source.  I would like to see it in context (or if he even said it at all - I have my doubts about it).  

A gentile can never be at home in the Catholic faith in the same way that a real Jєωιѕн convert can be.
