Here is a translation of the note that Pope Francis sent to the Chief Rabbi of Rome, Riccardo di Segni, for the feast of Passover, which starts today at sundown.
The Holy Father met Rabbi di Segni on March 20, during his audience with delegations from other Christian confessions and non-Christian religions.

A few days on from our meeting, and with renewed gratitude for your having desired to honor the celebration of the beginning of my ministry with your presence and that of other distinguished members of the Jewish community, I take great pleasure in extending my warmest best wishes to you and Rome's entire Jewish community on the occasion of the Great Feast of Pesach. May the Almighty, who freed His people from slavery in Egypt to guide them to the Promised Land, continue to deliver you from all evil and to accompany you with His blessing. I ask you to pray for me, as I assure you of my prayers for you, confident that we can deepen [our] ties of mutual esteem and friendship. - FRANCIS
