The innovators of psychological theories tried to understand man apart from the Bible and created unbiblical systems to explain the nature of man and equally unbiblical ways to change him. People like Sigmund Freud and Carl Jung undermined confidence in Christianity and established therapeutic systems directly opposed to God's word. Atheism, occultism, and acute antagonism towards Christianity were masked with high-toned scientific sounding psychological jargon. Freud observed neither humanity nor religion objectively. All humanly devised philosophies reveal more about the philosopher than the mysteries of life.
Therapeutic interventions seek to force compliance with the philosopher's perceptions of reality.
Under no circumstances is Freudian psychology useful to a Christian. He found the Christian Communion to be dull and lifeless, so he renounced Christianity. Jung did not follow his mentor, Dr. Freud, in denying all religions. Instead he concluded they were myths but contained some truth about the human psyche. Since he viewed all religions as containing some truth, Jung denied the authority of the Bible and Jesus' claim to be the only way of salvation.
