John 10:16

The other sheep in view refer to Gentiles outside the fold of Israel who would believe in Jesus (cf. John 10:3-4). This is one of a few intimations in the Gospels that a new body would replace Israel as the people of God in the present age (cf. John 17:20; Ephesians 2:11-22; Ephesians 3:6). These sheep, with those from Israel, would compose one fold, namely, the church (cf. 1 Corinthians 10:32). This rules out the possibility of a Jewish church and a Gentile church. That fold would have one shepherd, namely, Jesus, who would become, to change the figure, the Head of the church. Jesus knew these sheep (John 10:14-15) as well as those who would believe on Him in Israel, "this fold" (cf. Psalms 100:3).
