Hi Joe,
Thanks for your comments, it's nice to see you here.
Of course all the usual arguments against the Stratford man's authorship of the plays would be unaffected if it turns out that he had Jewish ancestors. If Amelia Bassano wrote the plays, the theological views or ancestry of Richard, John or William Shakespeare are of secondary interest, except as they would bear on a propaganda theory of the function of the Shakespeare plays in Elizabethan society.
However, I don't see the logic in your statement that the author's father could not have been Catholic. My objections are:
(1) Children do sometimes rebel against their parents' religion or beliefs, although I agree it's far more common that 'the apple doesn't fall far from the tree'. As an example from my own experience, my grandfather was a Marxist while my parents are capitalists. So I don't see any reason why William couldn't have harbored Jewish religious views, even if his father adopted a sincere Catholicism.
(2) The ideas of 'British Israel' had surfaced in Britain by this time, so there's no reason why British Protestants or even Catholics couldn't see themselves as heirs of the promises made to the Jews in Isaiah. Even before that, the Old Testament has always accompanied the New Testament in every Catholic bible.
(3) While Aaron is portrayed as racially Semitic, many others taking the role of 'hidden Jews' in the plays (such as Prospero or Friar Lawrence) are Northern Europeans. Thus, it's possible that the author did not view the distinction as fundamentally a racial issue.
As to the evidence that John Shakespeare was Catholic, there is his signed "
spiritual last will and testament" which was hidden in the rafters of his house and discovered in 1757. (At this link, author Steve Roth claims to have detected parallels to the hidden testament in the ghost's speech in Hamlet!!) We also have John Shakespeare's appearance on a Catholic recusancy list in 1792, suggesting a durable commitment. By way of circumstantial evidence, there is the fact (as discussed by
Peter Dickson) that:
Shakespeare’s parents were acquainted with or had family ties to some of the most notorious Catholics of the entire period: Edward Campion, the Cottoms, Edward Arden, John Somerville, and Richard Debdale in the 1580s. .... the Catesbys and Grants, and the Winters who sup- plied the leaders of the conspiracy to blow up King James while in Parliament, the notorious Gunpowder Plot, narrowly foiled in November 1605. William Shakespeare’s father (John) had business dealings with the Grant family and his mother was a cousin of Arden whose nephew was a Somerville and whose mother was a Grant and so on ...
Here we are not talking about ordinary “secret” Catholics, most of whom kept a low profile and conformed outwardly to the Anglican Church––earning the odd name of “Church Papists”––but about those fanatical in their loyalty to Rome, men willing to sacrifice and who in fact lost their lives in challenging the authority of Queen Elizabeth and the Anglican Church.
So now in opposition to all this, we have the informant James Langrake's accusation that John Shakespeare was a Jewish moneylender. It makes perfect sense that John Shakespeare would have wanted to hide those aspects, assuming they were true. And if the Shakespeares were bankers, it would go a along way towards explaining how they were able to afford such nice houses.
But if John Shakespeare was merely trying to conceal his Jewishness, he wouldn't have needed to become a Catholic fundamentalist just for that purpose!! That would be jumping from the frying pan into the fire.
