Christianity and the Outsider

What does Christianity have to say about the salvation of the African tribesman who died before the missionaries arrived, and the "e;great sorrow"e; of the Messianic Jew who grieves for family and friends who did not or will not acknowledge his Jesus as their Messiah? C. S. Lewis said these outsiders represent the "e;scandal of exclusivity."e; Jim Geiger is a Christian insider and fully committed to the exclusivity of Christ's atonement. However, he is suggesting an expanded Christology where:- The constant speed of light in E = mc2 corroborates the constant Christ of Heb 13:8. - Special and general relativity model special and general revelation. - The Christ of general revelation represents the hope of salvation for some of Christianity's outsiders.
