In the Saint Joseph Edition of The New American Bible, in The Gospel of Saint John , there was a footnote about “Other sheep”.
Other sheep: the Gentiles, possibly a reference to "God's dispersed children", destined to be gathered into one, or "apostolic Christians". The Savior came for the Chosen People. The Savior came for the Gentiles.
Why would the Gentiles be referred to as “apostolic Christians”?
