The "Course in Miracles" is a book and an associated workbook written (1965-1972) and edited by Helen Schucman (an atheist psychologist), with portions transcribed and edited by William Thetford. Schucman believed that an "inner voice", which she identified as Jesus, guided her writing.

The philosophy of the "Course in Miracles" is difficult to pin down but it suggests that the material world including our bodies do not exist. The main idea is that all perception is only an illusion created by a mind separated from God (Oneness).

The "Course" claims that somehow we chose to separate from God (Oneness) and that we can accept the atonement (return to Oneness) through forgiveness as defined by the Course.

The "Course" teaches that "true forgiveness" is to acknowledge that there is nothing to forgive. That is - whatever wrong we perceive never really happened. In other words, we have never really separated from God. Separation is an illusion; sin is an illusion; the material world is an illusion. The only thing that is real is love. miracles are expressions of love. The course can be summarized as : there is only one problem: separation and there is only one solution which is "true forgiveness"

Is the "Course in Miracles" a message from God? Is it a message like Psalms, the Quran, the Torah the Bible? Or is the "Course" the work of man or even the Devil?

This is the fundamental question that needs to be answered before one chooses to follow the teachings and methods found in the "Course in Miracles".

Using quotes from the Quran it is easy to show that the essential claims in the "Course in Miracles" totally contradict the Quran. Hence, we must conclude that the Course is not of God but of men or the work of Satan who is the enemy of all believers in the one God. The Quran states that Satan is our most ardent enemy.

O you who believe, you shall embrace total submission; do not follow the steps of Satan, for he is your most ardent enemy.
[Quran 2:208]

Here are a few of the claims in the "Course in Miracles" coupled with a response from the Quran. Each of the Course's claim are refuted by many verses in the Quran. I have selected just one representative verse from the Quran in the spirit of brevity.

The "Course" claims that Man's ego created the world. The Quran teaches that God created all things including this world.

Your Lord is God who created the heavens and the earth in six days then He settled on the throne. The night covers the day, as it pursues it relentlessly, and the sun, the moon and the stars are ordained through His command. Is it not to Him that all creation and all matters belong? Blessed be God, Lord of the worlds.
Quran[7:54]

The "Course" teaches Man is still in heaven with God.The Quran claims that man was created by God from clay

We created the human being from an extract of clay.
Quran[23:12]

The "Course" denies the reality of death. According to the Quran death is real. We are born, die, and are reborn according to the Quran.

He is the One who brought you to life, then He puts you to death, then He brings you to life. The human being is unappreciative.
Quran[22:66]

The "Course" claims Jesus' body was an illusion. The Quran says he was physical - from dust.

The example of Jesus with God is the same as that of Adam; He created him from dust, then said to him, "Be" and he was.
Quran[3:59]

Sin is an illusion according to the "Course". The Quran mentions sin often and sin has definate consequence.

Indeed! Those who earn a bad deed and have become engulfed by their wrongdoings, they are the companions of the Fire; therein they shall permanently remain.
Quran[2:81]

The "Course" also teaches that evil does not exist. It is an illusion that must be overcome by right thinking. In the Quran believers are admonished to forbid evil - it's hardly an illusion - just look around.

They believe in God and the Last Day, they advocate righteousness and forbid evil, and they hasten to do good. These are among the righteous.
Quran[3:114]

The "Course" teaches that there are no absolutes; truth is relative and is determined by one's experience. Right and wrong, truth and falsehood are the bedrock of the Quran - the ultimate Truth is God.

And do not confuse the truth with falsehood and conceal the truth knowingly.
Quran[2:42]

The Quran and the "Course" could not be more different in their messages. If we believe that the Quran is a message from God then common sense dictates that we must conclude that the Course in Miracles is the work of the evil one (Satan) or the work of men.

May peace be upon you, and may you use your God given intellect in the best way.

The worst creatures in God's reckoning are the deaf and dumb who do not reason.
Quran[8:22]
