BBC: Pope Benedict's plans to revive the Latin Mass, which includes prayers for the conversion of Jews, is causing concern among Catholic and Jewish groups about relations between their faiths.
Religious commentators predict that Pope Benedict will issue authorisation for wider use of the Mass - known as the Tridentine Mass - soon.
The Mass was celebrated for hundreds of years before being replaced by a liturgy celebrated in local languages, as part of reforms instigated after the Second Vatican Council in the 1960s.
The old wording has none of the Vatican Council thinking that reversed long-standing anti-Jewish views in the Church. Vatican II brought about a revolution in Catholic thinking, highlighting the ancient Jewish roots of Christianity and affirming God's love for the Jews.
Concern is now focused on traditional mass's Good Friday liturgy which contains a prayer "For the conversion of the Jews". The prayer reads:
"Let us pray also for the Jews, that the Lord our God may take the veil from their hearts and that they also may acknowledge our Lord Jesus Christ."
It refers to their "blindness" and prays for them to be "delivered from their darkness." Concerns over Pope’s Latin Mass move by Kathryn Westcott
