The prophets looked forward to the day when the Gentiles would worship Abraham’s Lord. However, the prophets did not understand this fully (Eph.3:4–6), nor did they see that these Gentiles would be the ones in God’s kingdom used to draw Abraham’s physical sons back to Him. All who believe in Jesus are heirs of the promise; there are no second-class citizens in His kingdom. The Father has adopted you as His own child if you believe in Christ.
Revelation 7 indicates that God’s people will include men and women from every tribe and tongue. The catholic church is the church that is enriched by thinkers from every background who preach the truth of Scripture, not the church that makes one geographical or cultural expression of the faith definitional for everyone else. Let us work for the catholicity of the church, finding a place for all faithful expressions of biblical truth.
