Questions and concerns have been raised following recent media reports about a statement that had been made in Canada by the Superior of the Society of Saint Pius X that “the Jews” are the "enemies of the Church". The Canadian Conference of Catholic Bishops notes that such remarks are not in accordance with the teaching of the Catholic Church. As the spokesperson for the Holy See, Father Federico Lombardi, S.J., has said when commenting on the statement, “It is absolutely unacceptable, impossible, to define the Jews as enemies of the Church.”
The Second Vatican Council taught in Nostra Aetate, its Declaration on the Relation of the Church to Non-Christian Religions (no. 4): “God holds the Jews most dear for the sake of their Fathers; he does not repent of the gifts he makes or of the calls he issues – such is the witness of the Apostle [Paul].... [T]he Church, mindful of the patrimony she shares with the Jews and moved not by political reasons but by the Gospel's spiritual love, decries hatred, persecutions, displays of anti-Semitism, directed against Jews at any time and by anyone." This teaching has been reiterated time and time again by Popes John Paul II and Benedict XVI.
The Canadian Conference of Catholic Bishops denounces all forms of anti-Semitism, and rejects assertions such as those reported to have been made by the Superior of the Society of Saint Pius X, which is a schismatic group not in communion with the Catholic Church.
