Christian Science

Christian Science is also known as The First Church of Christ, Scientist. That title refers to the movement’s mother church in Boston, Massachusetts.

Branches may call themselves First Church of Christ, Scientist, Second Church of Christ, Scientist, and so on, but only the mother church may use “The” in front of the name.

The church is sometimes confused with ‘Religious Science,’ or with the ‘Church of Scientology’.

Founder Mary Baker Eddy (1821 – 1910) described Christian Science as a return to “primitive Christianity and its lost element of healing.”

In her book Science and Health (1875) Eddy teaches that sickness is an illusion that can be corrected by prayer alone. The book became Christian Science’s central text, along with the King James Bible.

However, the movement neither represents science, nor Christianity.

The Bible does not teach what Christian Science claims it teaches. See our research resources on faith healing.

Christian Science: Theologically a Cult of Christianity

Christian Science Mother Church, Boston, Massachusetts
Christian Science rejects and/or redefines key doctrines of the Christian faith, including those on the trinity and on the deity of Christ.

While it uses Christian terminology it completely reinterprets those terms.

For instance, in Christian Science:

  • God is not personal, but rather ‘divine principle.’ In her writings, Eddy used the terms Mind, Spirit, Mother, Intelligence, Substance, Soul, Principle, Life, Truth, Love as synonyms for God. She denied the doctrine of the Trinity, saying “Life, Truth, and Love constitutes the triune Person called God….God the Father-Mother; Christ the spiritual idea of sonship; divine Science or the Holy Comforter.” 1
  • Jesus is not God. The incarnation and bodily resurrection of Jesus Christ did not occur
  • The Holy Spirit is Christian Science
  • Scripture is not inerrant
  • Sin, death and evil do not exist
  • Sickness and death are illussions, the result of false beliefs
  • There is no literal, physical evidence of the material universe

While she claimed that “the Bible has been my only authority,” 2 Mary Baker Eddy also taught the Bible was corrupted, and said that Science and Health is the “first book” which has been “uncontaminated by human hypotheses.” 3

Therefore, though the movement claims to be a return to early Christianity, Christian Science is theologically a cult of Christianity.

Quackery, Religious Exemptions, and Preventable Deaths

In many U.S. states the Federal Government has granted Christian Science religious exemptions which, in the eyes of many, has led to needless suffering and preventable deaths.

In the 1970s, Idaho, like numerous other states incentivized by the federal government, enacted a religious exemption for parents who believe in faith-healing. The federal government was responding to pressure from the First Church of Christian Science, and no one seems to have grasped that children could and would die from such an exemption. The only explanation I can offer is that was part of the Pollyanna era of American history when everyone believed at some level that religious believers wouldn’t harm a child.

Such exemptions open the door to the deaths of children from ailments with known and tested treatments, from food poisoning to diabetes, pneumonia, and leukemia. The Church of the First Born and the Followers of Christ are two of the most ardent believers against medicine, and at one time, they populated Oregon, where prosecutors discovered in the 1990s to their horror that they could not prosecute them for the preventable deaths of children. Since then, Oregon has dramatically narrowed its medical neglect exemptions and prosecuted some of the worst cases, with a major manslaughter conviction in 2014.

While Oregon finally made strides in protecting its children, the number of deaths in Idaho escalated. Why? Because Idaho has created a legal paradise for believers in faith alone.

  • The Christian Science Holocaustoffsite [Contra] By Gerald Bergman. Article on the website of the New England Skeptics’ Society.

    Many churches teach that to use medical care is a violation of God’s law, although the record of religion caused medical deaths is probably held by the Christian Science Church founded by Mary Baker Eddy over a century ago. No one knows how many persons have died prematurely as a result of rejecting medicine on religious grounds, but the number is likely in the tens-of-thousands.

    Of all the Biblically-based cults in America today, Christian Science is one of the most interesting. Not only does it deny the essential doctrines of Christianity but it has also completely reinterpreted the Bible. It drastically redefines the Bible’s culture and terminology and rips thousands of Scriptures out of their historical and Biblical contexts. The result is a non-Christian mixture of metaphysical and philosophical thoughts. Christian Science is so foreign to the Bible that if it didn’t use words like Jesus, Trinity, Love, Grace, Sin, etc., you’d never suspect it had anything to do with the Bible at all. Additionally, the book Science and Health with Key to the Scriptures, which is the Christian Scientist’s mainstay of spiritual knowledge, reads with a rhythm of pseudo-logical statements that has the tendency to dull the senses when read long enough. Is Christian Science Christian? Definitely not.

  • Christian Science on Trial: Religious Healing in Americaoffsite By Rennie B. Schoepflin. “The 1920s witnessed an unsteady truce between American medicine and Christian Science. The ambivalence of many Americans about the practice of religious healing persisted, however. In Christian Science on Trial we gain a helpful historical context for understanding late–twentieth-century public debates over children’s rights, parental responsibility, and the authority of modern medicine.” In its review of the book, The New England Journal of Medicine says, “This book is not so much a critical assessment of Christian Science as it is a densely researched narrative of how this unusual, but enduring, form of medicine and religion developed. … Despite its fresh historical detail, the story might have been more compelling if Schoepflin had spent more time examining why, after a 50-year detente, Christian Science has suffered increasingly frequent attacks since the 1980s. … The current debates probably revolve around the philosophical and theological problems with radically spiritualized worldviews that deny the reality of material existence.”
