From the back cover:
Mrs. Eddy's 1898 message to The Mother Church brings out the clear distinction between pure, monotheistic Christianity and the pantheistic concept that mind is in matter or in forces of nature. It presents an unequivocal affirmation of one supreme God - one infinite Mind, which is Spirit, not matter, and totally good.
Turning to the First Commandment and the teaching and practice of Christ Jesus, Mrs. Eddy rejects the possibility of any genuine power opposed to Spirit. She highlights Jesus' definition of evil as a lie and encourages us to deny and overcome it through an understanding of the omnipotence of God.
This message elucidates scientific Christianity - the allness of Spirit and man's true nature as Spirit's perfect image.
