"However, in what does that curse consist. Surely it cannot be that there is a collective guilt of the Jewish race for the sin of deicide. For only those individuals are responsible for the sin who knowingly and willingly brought it about. Jews of today are manifestly not responsible for that sin. The curse is of a different nature, and corresponds to the greatness of the vocation of the Jewish people as a preparation for the Messias, to the superiority of their election, which makes them first in the order of grace."
From the post you gave. Nothing can be interpreted here as being "heretical." In fact, the Credo of the Council of Trent says we must interpret Sacred Scripture ONLY in full accord with the Fathers of the Church. I suggest you read what they said about the responsibility of the Jews in Christ's crucifixion.
I am no theologian. You made no theological argument. You posted something as saying something you have mistakenly attributed falsely.
If there is something theologically wrong with it, prove it. The burden of proof is on you.
It appears to me, in my cursory reading, to be more or less in accord with Tradition, to which we are all bound. Don't make the Vatican II documents say more than they do.
*The sspx's official American Organ, the Angelus, teaches precisely that which an Ecumenical Coucnil condemns.
On the matter of the Jews being cursed, do you side with the Ecumenical Council Magisterium or do you side with the schismatic sspx?
