Liturgical and ritual forms express man's religious faith and his attitude to that faith. Both the Jewish and the Christian liturgies are, therefore, expressions of belief in God and in his revelation. Both, in a sense, actualize the presence of God, which means that Salvation History finds its fullest expression in liturgical worship. This worship is one of the most powerful means of religious education. We are living at a time of renewal and change, when liturgy is being adapted to the needs of man to-day. The Vatican Council has urged us to return to our biblical and primitive sources, and to seek there for more adequate and authentic forms of liturgical expression. The aim of this issue of SIDIC is to provide material that may prove helpful to those who are working for liturgical renewal, by giving them a deeper understanding of these sources. Liturgy has too often been a means of transmitting mistrust and hostility, particularly between Christians and Jews. We hope that the articles presented in this issue will contribute to a greater openness and a deeper understanding between them. The Editors
