MARY BAKER EDDY twice makes the definite statement that "Christianity is the chain of scientific being reappearing in all ages, maintaining its obvious correspondence with the Scriptures and uniting all periods in the design of God" (Science and Health with Key to the Scriptures, p. 271; The First Church of Christ, Scientist, and Miscellany, p. 279).
The appearing of this "chain of scientific being" is seen in the great revelation of God's law which came to Moses on Mount Sinai, and which took form in the Ten Commandments written on two tables of stone. This is the first record of the appearing of God's Word in such fullness as to stabilize human action and to furnish a righteous guide to human endeavor.
Bible students are familiar with the record of this revelation and the manner of its presentation to the people. Moses was called of God to come up to the mount, and after a fast of forty days he received the Ten Commandments on two tables of stone which had been prepared. This first record, however, was destined not to be delivered to the people; for Moses became angry when he saw the idolatry into which the Israelites had fallen during his absence, and he threw the tables of stone to the ground, thus breaking them. Again God called Moses to come up on the mount, to hew two tables of stone like the first, and to make an ark of wood in which to place them. When Moses followed this further guidance and placed what had been revealed to him in the ark, it became the law to the children of Israel. To this day these commands are acknowledged as a firm basis of civil and social law.
