The founder of the church, Mary Baker Eddy, was its first pastor. Her sermons healed those in the congregation. But later, when she found the sermons presented by others were not healing and contained too much of what she termed a human hypotheses, she ordained the Bible and Science and Health with Key to the Scriptures as the pastor of the Christian Science church. Using only these two books as its source, the lesson, or sermon, is uncontaminated and unfettered by human hypotheses” (Christian Science Quarterly).

The Pastor’s lesson or sermon for each week is outlined in the Christian Science Quarterly and is studied throughout the week by Christian Scientists around the world. The Pastor’s lesson or sermon is then read in Christian Science churches on Sunday by two lay readers.

The Bible, Science and Health, and the Christian Science Quarterly may be purchased on-line at or at any Christian Science Reading Room.
