Book excerpt: What's special about Oneness Pentecostals? In this penetrating analysis of Oneness theology and practice, Gregory Boyd reveals the experience of four years of personal involvement in a Oneness church. Although Oneness Pentecostals' belief in Christ's deity establishes some common ground with other Christians, their aggressive denial of the Trinity has nonetheless fostered their indisputably sub-Christian ideas about God's character, about salvation, and about Christian living.
