As a side note I attended most of the services during Great and Holy Week as also the Pascha Liturgy. I don't remember any of these words or hymns being sung. I also think its worth noting that the priests in question are clearly referred to as dissidents. That casts an instant cloud over their credibility. One is even identified as belonging to an "Ecumenical Orthodox Church." Translation he is at least schismatic and quite probably a heretic.
A group of 12 Orthodox priests have called on their Church to review its longstanding theological positions toward Jews and the State of Israel, and to excise anti-Semitic passages from its liturgy.
The dissident priests made their demands in a 12-point declaration adopted during a weeklong visit to Israel that is meant to spur debate in the Orthodox Christian world and to challenge centuries-old anti-Semitic views.
"Sadly, there are some Orthodox Christians who propagate disgusting anti-Semitism under the banner of Orthodoxy, which is incompatible with Christianity," said Rev. Innokenty Pavlov, professor of theology at Moscow's Biblical Theological Institute.
"We have to raise our voices and call on Orthodox laity and the Church leadership to formulate an official position of the Orthodox Church toward our relations with Judaism, as it was formulated a few decades ago by the Catholic Church," he added, referring to the Second Vatican Council of 1962 to 1965...
...Unlike the Catholic and Protestant churches, the Orthodox Church has never removed anti-Semitic passages from its liturgy, which still refers to Jews as Christ killers, said Dr. Dmitry Radyehsvky, director of the Jerusalem Summit, a conservative Israeli think tank that co-sponsored the visit.
He said the anti-Semitic passages were most conspicuous during Easter services, and included statements such as "the Jewish tribe which condemned you to crucifixion, repay them, Oh Lord," which is repeated half a dozen times, and "Christ has risen but the Jewish seed has perished," as well as references to Jews as "God-killers."
Having said all this I will concede with some pain that in a few corners of the culturally Orthodox world, antisemitism is alive and at times it has been abetted by members of the Church. I think the various Orthodox Churches would do well to formally condemn this noxious bigotry in no uncertain terms.
