LG 25 says that decrees from a properly constituted ecumenical council are infallible. The traditionalist blather about Vatican II being just a "pastoral council" is their way of pretending that the council decrees can be ignored. Cafeteria Catholicism, traditionalist style.

The teaching of the Roman Catholic Church is: "In the first place we must recall the people to whom the testament and the promises were given and from whom Christ was born according to the flesh.(Romans 9:4-5) On account of their fathers this people remains most dear to God, for God does not repent of the gifts He makes nor of the calls He issues.(Romans 1l:28-29.) But the plan of salvation also includes those who acknowledge the Creator." -- LG 16

You traditionalists hate to admit it, but TEACHINGS CHANGE. To deny this is to deny historical fact. Your "teaching" has a loving, merciful, just God sending Jews to hell for exactly the same reason the Nazis sent Jews to Auschwitz: because they are Jews.
