So the Church was wrong for 2000 years but now they finally got it right.
I think the curse against the Jews was NOT because they were responsible for His death, we all were after all; but because they who had the True Faith denied Jesus when He came. He was too poor for them, they wanted a powerful, wordly Savior. Their Messiah came and they know it, their stiff necks and pride won't allow them to face the truth. If these current VII "popes" were true, they would tell them that, as the popes have always told them in the past.
It was the Romans that actually nailed Our Lord to the Cross, therefore in my mind, I believe those words "Father forgive them for they know not what they do", were meant for them. The Jews knew what they were doing, because they were under the Law and they had the prophesies, studied them and knew them, prophesies that Jesus Christ fulfilled.
