God would never come to his people through two separate religions that disagree on the most crucial point of all. There is only one continuing revelation § 839, called Jewish when it was the religion of the Judean people, and Catholic when it was opened to all the world. God changed the names of Abram, Sarai, Jacob and Simon when their relationship to him changed, and he has changed the name of his community of faith. Rabbi Yeshua came to fulfill, to complete the Old Covenant, which remains an everlasting part of salvation history. More about continuity.
Second Exodus seeks to help all Israel discover her Mashiakh. It is directed primarily to Catholics who may someday encounter an inquiring Jew. If an inquiring Jew approaches a Catholic and asks about the Church, and the Catholic knows how to explain the Church as the synagogue transformed by God's Messiah, both may have a small role in a vast event § 674. More about the mission.
Most Second Exodus visitors are already Catholic. Some are cradle Catholics, and some are converts from Judaism or Protestant denominations. They come for the Catholic teaching. Some of them read Hear O Israel to discover the Church's Jewish origins. Others on their Catholic journey come to find The Way forward. Wherever you are in your journey, you and all are welcome!
