September 13, 1903. Charity is good and peaceful, but it must not
cover iniquity; just as long as you compromise with error, just so
long will the error stick to you. In teaching students I have always
uncovered the error to them; that is what should be done, and not
all the pleasant things said only. ‘He that covereth iniquity (his sins)
shall not prosper.’
    The error that is holding them must be uncovered to students so
they can overcome it.  Mary Baker Eddy   (Oakes, Richard, Course In Divinity and General Collectanea, p.11)

Hate is a form of the death argument, sapping.  Mary Baker Eddy   (Carpenter, Gilbert, Fragments Gathered From Unpublished Items Ascribed to Mary Baker Eddy, p.81)

The law of God includes a law that annuls every false claim, and we know it and must use it. Mental activity must be tranquil — not lazy; it must express force, be exact and it must know the reality of man’s oneness with God, and the utter unreality of evil in all its forms of beliefs. Know there is no mental or materi­al poison; no substance or mind to contain or manifest poison, irritation or inflammation; no organism or substance that can give forth impurities; no impeded circulation or imperfect action. We cannot be made apathetic or forgetful, for God is our guide and instructor.   Mary Baker Eddy   (Carpenter, Gilbert, Collectanea of Items By and About Mary Baker Eddy, p.131)

Mrs. Eddy once wrote, “There is nothing in me that corresponds with, or responds to any form of evil.”   Mary Baker Eddy   (Carpenter, Jr., Gilbert, 500 Watching Points, #63)

As I am the reflection of Life, which is the only intelli­gence and action, I am always acting, and never acted upon by fear, anxiety, discouragement, thought-transference, nor any other claim of evil. The action and intelligence which I express lead me to see the right way in everything.   Mary Baker Eddy   (Carpenter, Gilbert, Essays On Christian Science, (Red Book), p.55)

TRUTH-HEALING – 9 

This spirit of sacrifice always has saved, and still saves mankind; but by mankind I mean mortals, or a kind of men after man’s own making. Man as God’s idea is already saved with an everlasting salvation. It is impossible to be a Christian Scientist without apprehending the moral law so clearly that, for conscience’ sake, one will either abandon his claim to even a knowledge of this Science, or else make the claim valid. All Science is divine. Then, to be Science, it must produce physical and moral harmony. (Eddy, Mary Baker, Miscellaneous Writings, p.261:23-32)

TRUTH-HEALING – 8

In this law of justice, the atonement of Christ loses no efficacy. Justice is the handmaid of mercy, and showeth mercy by punishing sin. Jesus said, “I came not to destroy the law,” — the divine requirements typified in the law of Moses, — “but to fulfil it” in righteousness, by Truth’s destroying error. No greater type of divine Love can be presented than effecting so glorious a purpose. (Eddy, Mary Baker, Miscellaneous Writings, p.261:16-22)

TRUTH-HEALING – 7

According to divine law, sin and suffering are not cancelled by repentance or pardon. Christian Science not only elucidates but demonstrates this verity of being; namely, that mortals suffer from the wrong they commit, whether intentionally or ignorantly; that every effect and amplification of wrong will revert to the wrong-doer, until he pays his full debt to divine law, and the measure he has meted is measured to him again, full, pressed down, and running over. Surely “the way of the transgressor is hard.” (Eddy, Mary Baker, Miscellaneous Writings, p.261:6-15)
