Red Letter Christians is a movement that emphasizes following Jesus’ words, especially from the Sermon on the Mount, and links them to political causes while claiming to be apolitical. While their focus on Jesus’ teachings is commendable, the Bible calls Christians to value all Scripture equally, understanding both Old and New Testaments in context, and recognizing that Jesus’ instructions were primarily for personal and spiritual life, not government policy. Jesus Himself stated that His kingdom “was not of this world” (John 18:36). The movement’s approach highlights the risk of isolating parts of Scripture. While Christians should endeavor to live out Jesus' teaching in all areas of life, we must handle God's Word honestly and in its entirety.
The organization Red Letter Christians describes itself as "a movement of believers who live out Jesus' counter-cultural teachings." It began in 2007 as a reaction against what its founders, Tony Campolo and Shane Claiborne, perceived as the term “Evangelical” becoming associated with a voting bloc. The name Red Letter Christians points to their primary commitment to following the words of Christ, which many Bibles print in red. Today, the organization runs a blog, sends daily devotional emails, distributes a bimonthly newsletter email, hosts a radio show and podcast, and organizes an annual meeting for its network of speakers and authors. But the Bible reveals principles that contrast with the organization’s approach.
Red Letter Christians’ organizational mission is centered around Jesus’ words, especially His Sermon on the Mount, but Jesus quoted Old Testament Scriptures. He indicated that He was the fulfillment of the Old Testament law. So clearly Jesus agreed with Paul’s words to Timothy about “all Scripture” being “God breathed” (2 Timothy 3:16-17; emphasis added).
As we speak with others about Christ, it’s common practice to recommend that Bible neophytes start with, say, the Gospel of John. But “start” is the key word. We should always impress upon others that the entire Bible is worthy of study. And we should live that truth by studying the whole Bible, not just the New Testament. God’s wisdom is at our fingertips—whether in black ink or red.
