It was definitely not positive. Actually, read the article. It has many good details about the prayer, such as its origin, the fact that it was the only prayer for which priests did not kneel, etc.
There was massive anti-Semitism among the Northern European states, including France, even though of course the threat to Europe even at that time was actually the Muslims.
However, there were a lot of other factors, including the influence of the highly anti-Semitic Arianism, the usual jealousy of a less cultivated population against a more developed group, etc. This appeared in the Franco Roman rite, which was imposed by Rome on all of Europe, including places such as Spain, which had had a different, more Byzantine rite.
It was retained, along with not kneeling for this one petition, by the Council of Trent.
So there was definitely a need for reform, and originally, when VII began, many people thought that it would deal with just a few anomalies such as this. But of course, it went wild and completely changed the entire liturgy, to the point where I’m not even sure we pray for the Jews anymore. (The “Palestinians” might not like it.)
I’m not buying it. The Catholic Faith taught...until VII...that the Jews were responsible for the death of Jesus. The apostles were hiding for fear of the Jews. The Jews, to this day, do not recognize Christ. They did have the faith and they were blind. The prayer did not pray to hate Jews; it prayed for their conversion. The prayer may not have been PC, but it was the truth.
Once again, VII and its false ecumenism has changed the Church..and not for the better.
