36. From the Christian confession that there can be only one path to salvation, however, it does not in any way follow that the Jews are excluded from God’s salvation because they do not believe in Jesus Christ as the Messiah of Israel and the Son of God. Such a claim would find no support in the soteriological understanding of Saint Paul, who in the Letter to the Romans not only gives expression to his conviction that there can be no breach in the history of salvation, but that salvation comes from the Jews (cf. also Jn 4:22). God entrusted Israel with a unique mission, and He does not bring his mysterious plan of salvation for all peoples (cf. 1 Tim 2:4) to fulfilment without drawing into it his "first-born son" (Ex 4:22). From this it is self-evident that Paul in the Letter to the Romans definitively negates the question he himself has posed, whether God has repudiated his own people. Just as decisively he asserts: "For the gifts and the call of God are irrevocable" (Rom 11:29). That the Jews are participants in God’s salvation is theologically unquestionable, but how that can be possible without confessing Christ explicitly, is and remains an unfathomable divine mystery. It is therefore no accident that Paul’s soteriological reflections in Romans 9-11 on the irrevocable redemption of Israel against the background of the Christ-mystery culminate in a magnificent doxology: "Oh, the depth of the riches and wisdom and knowledge of God! How inscrutable are his judgments and how unsearchable his ways" (Rom 11:33).
