The New Testament Reign of God welcomes non-Christians as common seekers after a truth fully revealed in Jesus Christ but experienced in different historical settings by other religions as well. The Kingdom was consistently made available to outsiders. Jesus said to a Roman centurion, “Truly I tell you, in no one in Israel have I found such faith.” (Mat.: 8:10) To a Canaanite woman he declared in healing her daughter, “Woman, great is your faith! Let it be done for you as you wish.” (Mat. 15:21-28). Jesus conversed with a foreigner, a Samaritan woman, (Jn. 4:7-15) who sought “living water” and elsewhere cited the example of the “good Samaritan” who had pity on a wounded robbery victim (Lk. 10: 29-37). Pagans, outsiders, or foreigners were consistently welcomed by Jesus, and at the final Passover dinner he told his followers he would not eat the Passover again “until it is fulfilled in the kingdom of God.” (Lk 22: 16).
This, in broad outline, is a reading of what the Reign of God means. Many world theologians of recent decades understand the kingdom to be freely offered to both believers and members of other religions. If their lives and beliefs reflect what Jesus preached, they too are witnesses to the Kingdom in global settings. This moves considerably beyond Rahner’s “anonymous Christians” and the classic confines of Exclusivists and Inclusivists, and affirms that God’s loving reach extends to other religions, most of which the earthly Jesus would not have encountered in the Middle East of his time.
