Is Christian Science biblical Christianity?

Christian Science explicitly rejects the classical Christian understanding of God as three distinct persons — Father, Son, and Holy Spirit — sharing one being, describing that understanding as suggesting "polytheism." But the New Testament repeatedly speaks of Father, Son, and Spirit as distinct persons acting toward one another, not as one person under three names. Jesus commands baptism "in the name of the Father and of the Son and of the Holy Spirit" (Matthew 28:19) — into one name shared by three, not three separate names or three roles of one actor. The Father speaks to the Son and calls him "my beloved Son" at his baptism; the Spirit descends visibly at the same moment — three distinct participants in a single scene, not one person appearing three ways in sequence. Rejecting the classical formulation is not a minor disagreement about a later theological term absent from the Bible's own wording; it is a rejection of the relational language the New Testament itself repeatedly uses for God.

John's Gospel identifies the divine Word directly and personally with the man Jesus, not with a separate idea Jesus merely expressed: "the Word became flesh" (John 1:14) — the Word himself, not an idea distinct from him, became flesh. Colossians goes further: "in him the whole fullness of deity dwells bodily" (Colossians 2:9) — the fullness of deity dwells in Jesus bodily, in his own person, not alongside him as a separable principle he illustrated. Christian Science's "duality of Jesus the Christ" describes something closer to a man who successfully demonstrated a divine idea than to historic Christianity's confession that Jesus of Nazareth is himself God the Son, in one person.

Genesis records God's own verdict on the material creation he made: "God saw everything that he had made, and, behold, it was very good" (Genesis 1:31) — very good, not illusory. After his resurrection, Jesus specifically corrects the disciples' impulse to treat him as less than physically real: "a spirit doesn't have flesh and bones, as you see that I have" (Luke 24:39) — appealing to flesh and bones as proof against exactly the kind of "matter is not ultimately real" reading Christian Science teaches. And Scripture treats sin as a real, culpable condition rather than a mistaken belief to be corrected: "if we say that we have no sin, we deceive ourselves, and the truth is not in us" (1 John 1:8). This is a foundational, not peripheral, difference: it changes what the crucifixion accomplished, what the resurrection demonstrated, and what sin, sickness, and death actually are.
