When Mary Baker Eddy discovered the Science of Jesus' teachings, she saw that it was based upon divine Principle. In order that this Science might be more generally recognized and its Principle understood, the wise Leader of Christian Science established within the organization of The Mother Church a Board of Lectureship. In a letter to this same Board Mrs. Eddy instructs its members to go forth and challenge chance. She says (The First Church of Christ, Scientist, and Miscellany, p. 248), "You go forth to face the foe with loving look and with the religion and philosophy of labor, duty, liberty, and love, to challenge universal indifference, chance, and creeds." "Chance" is defined in a dictionary as "something that befalls us as the result of unknown or unconsidered forces."
In the Bible it is recorded that the superstitious Athenians erected an altar "TO THE UNKNOWN GOD" (Acts 17:23). In erecting this altar they believed they could eliminate the chance of offending a god who was unknown to them. Paul, a true follower of the Christ, challenged this superstitious belief of the Athenians by declaring, "Whom therefore ye ignorantly worship, him declare I unto you." It is this same message, the message of unerring divine Principle, that Christian Science is declaring today. Only an understanding of the true God, which Science reveals, can eliminate the belief in chance.
In the Glossary of the textbook, "Science and Health with Key to the Scriptures" by Mrs. Eddy, under the word unknown this definition is found (p. 596):
