Saint Margaret Mary Alacoque was a seventeenth century French nun and Christian mystic who is famous primarily for her visions surrounding the Sacred Heart of Jesus, but she also had a little bit to say on the subject of the jews.
She states for example that:
‘Even sanctity, before which the Jews prostrated in the midst of the thunderbolts of Sinai, before which the cherubim veiled themselves with their wings, has not the highest claim to man's adoration. Love wields the sceptre.’ (1)
By which she means that the jews prostrated themselves before a divinity in a thunderstorm on Mt. Sinai but that this wasn’t really God or at least not the true essence of God and thus they are a fallen people or at least on a lower spiritual plane than Christians.
She continues by stating in her ‘Autobiography’ that:
‘It is one of the new proofs that science furnishes of the long relations of the Jewish people with the Egyptians; for we know that in the Holy Scripture was the same with the Romans, and even with the Etruscans, called by Cicero "the most religious of all nations."’ (2)
So, in essence Saint Margaret Mary Alacoque sees the jews as what Arnold Toynbee characterised as a ‘fossil people’ adhering to a ‘fossil religion’ and thus were spiritually inferior to non-jews who do not adhere to such a faith and are the people of the New Covenant rather than the Old Covenant.
