> Let us pray also for the perfidious Jews: that our God and Lord would remove the veil from their hearts: that they also may acknowledge our Lord Jesus Christ.
> Almighty and everlasting God, who drivest not away from Thy mercy even the perfidious Jews: hear our prayers, which we offer for the blindness of that people: that, acknowledging the light of Thy truth, which is Christ, they may be rescued from their darkness.
> Through the same Jesus Christ, thy Son, Our Lord, Who liveth and reigneth with thee in the unity of the Holy Ghost, God, world without end.
> R. Amen.
This prayer has been suppressed by the Vatican 2 church as far as I'm aware; the word "perfidious" means: "Guilty of perfidy; violating good faith or vows; false to trust or confidence reposed; treacherous; faithless".
Hence it would seem to be a modern error to consider the Jewish people as "faithful", from a traditional Christian perspective? Yet naturally no excessive and additional conflict should be intended beyond that which exists by nature of the continued rejection of Jesus as Messiah.
Yes. If their conversion is sincere, God will accept them and their SOUL will go to Heaven. The BODY, however, still needs to go in the oven.
