It is evangelistically disastrous when, in an effort to reach Muslims, references to Jesus as "the Son of God" are removed from New Testaments. To tamper with the Sonship of Jesus is to undermine such essential doctrines as the Trinity, the incarnation, the deity of Christ, the humanity of Christ, the atonement, etc. And yet amazingly there are major players within evangelicalism and missions who are advancing this deadly tactic.
