LMS Chairman: Prayers for the Jews in the Liturgy of the Hours
'And for Vespers on Wednesday of the second and fourth weeks of Easter we find this prayer: "[O God], who chose your Son's first disciples from among the Jewish people, reveal to the children of Israel the reciprocal promise (repromissio) made to their fathers." (This is a reference to the promise announced to their fellow-Jews by Peter and the other apostles at Pentecost, that they would receive the Holy Spirit and salvation in return for believing in Christ and accepting baptism.)
Very explicit, on the other hand, is the Vespers prayer for Easter Sunday - the most important of all the annual Catholic feasts. It addresses Jesus in these words: "May Israel recognize in you the Christ she is hoping for (Israel in te Christum spei suae agnoscat), and may the whole earth be filled with the knowledge of your glory." This prayer is then repeated on the evenings of the
third and fifth Sundays of the Easter season.'
