Both Jews and Christians recognize in Abraham their father in faith (cf. Gal 3: 7; Rom 4: 11ff.), and they look to the teachings of Moses and the prophets. Jewish spirituality, like its Christian counterpart, draws nourishment from the psalms. With St Paul, Christians are convinced that "the gifts and the call of God are irrevocable" (Rom 11: 29; cf. 9: 6, 11; 11: 1ff.). In considering the Jewish roots of Christianity (cf. Rom 11: 16-24), my venerable Predecessor, quoting a statement by the German Bishops, affirmed that "whoever meets Jesus Christ meets Judaism" (Insegnamenti, Vol. III/2, 1980, p. 1272).
