Jaynek, so would you agree that that article is accurate up to its author's reference to the тαℓмυd? Would it be correct to affirm that our Lord's actions, during His last supper when He taught us to repeat them in memory of Him, are rooted in the Jєωιѕн passover? Would that description be accurate?
I, personally, would not use the expression "rooted in" to describe the relationship. I think it has the wrong connotations, since it comes from the imagery of a plant growing naturally from its roots. The Mass did not come about by a natural process. The institution of the Sacrament of the Eucharist was a supernatural intervention into human history by God. Our Lord fulfilled the truth prefigured by the Jєωιѕн Passover and this is reflected in the Mass.
Of course, there is a connection between Easter and Passover. In most languages, they are even the same word. In your own Italian, for example, both are "Pasqua" and the Jєωιѕн celebration distinguished as "Pasqua Ebraica". During His time on earth, Our Lord lived as a Jєω of that time. He worshipped at a ѕуηαgσgυє, kept the Sabbath, and celebrated the Passover (and did so at the Last Supper). This is an aspect of the mystery of the Incarnation.
However, I would be very cautious about what any post-conciliar author has to say about this subject. There are too many wrong ideas concerning Jєωs and Judaism at this time. Even in the absence of glaring errors, I would expect subtle mistaken assumptions or implications. In this thread, several members have recommended a pre-conciliar work on this subject. If it is something you have an interest in, that seems like a good resource.
