For Jews engaging with Orthodox Christians, it is important to remember that the first rule of interreligious dialogue is allowing “others” to define themselves. That means being especially attentive to the ways in Orthodox Christians differ from the Western churches with which Jews are most familiar. It requires understanding, inter alia, not only theological differences, but also the “ecosystem” of the Orthodox Church, autocephaly and how decisions are made, and the role of the patriarchs. While Pope John XXIII could order a change in the Good Friday liturgy, that is simply not how it works in Orthodoxy. Expecting Orthodox Christians to behave like Roman Catholics would not be a constructive strategy. Rabbi Sandmel
