Who will we see at the Resurrection?

We have very solid hope that we will see our loved ones at the resurrection. Our Christian faith tells us that the basis of our hope is the Lord Jesus Christ, who died for us sinners. Even more, this hope will not disappoint us, because the who love of God has been poured out into our hearts through the holy Spirit (cf. Rom. 5:5-8).

The basis of your concern seems to be the fact that your friend was Jewish. Now, we do believe that all salvation comes through Christ and His Church (cf. Acts 4:12), but the Church also acknowledges that elements of sanctification exist outside of the Christian faith—in other words, God’s mercy is by no means limited to the visible Church, but rather all those who strive to be faithful to whatever truth they have been given may be saved. And this all pertains in a singular way to the Jewish people, who have a strong historical connection with Christians. Here is part of what the Catholic Church had to say at Vatican II (1962-65) concerning the Church’s connection to the Jewish people:

As the sacred synod searches into the mystery of the Church, it remembers the bond that spiritually ties the people of the New Covenant to Abraham's stock.

Thus the Church of Christ acknowledges that, according to God's saving design, the beginnings of her faith and her election are found already among the Patriarchs, Moses and the prophets. She professes that all who believe in Christ-Abraham's sons according to faith (6)-are included in the same Patriarch's call, and likewise that the salvation of the Church is mysteriously foreshadowed by the chosen people's exodus from the land of bondage. The Church, therefore, cannot forget that she received the revelation of the Old Testament through the people with whom God in His inexpressible mercy concluded the Ancient Covenant. Nor can she forget that she draws sustenance from the root of that well-cultivated olive tree onto which have been grafted the wild shoots, the Gentiles.(7) Indeed, the Church believes that by His cross Christ, Our Peace, reconciled Jews and Gentiles. making both one in Himself.(8)

The Church keeps ever in mind the words of the Apostle about his kinsmen: "theirs is the sonship and the glory and the covenants and the law and the worship and the promises; theirs are the fathers and from them is the Christ according to the flesh" (Rom. 9:4-5), the Son of the Virgin Mary. She also recalls that the Apostles, the Church's mainstay and pillars, as well as most of the early disciples who proclaimed Christ's Gospel to the world, sprang from the Jewish people (Nostra Aetate, no. 4). . . .
