Or,..was Sigmund Freud, his mentor, with whom he later dis-associated himself? It is not clear what either of them thought...about 'God' or religious faith. Many have taken some of Freud's statements as indicating that he was an athiest. I don't think so, but that is my opinion. The same for Jung. I just think that neither of them wanted to go into it. They were both very much into the human mind and "psyche". Whatever their beliefs were, they kept it separate from their studies of the human mind.

He was when he was Jung, at least. In actual fact, who knows. He could be so vague and even contradictory in his writing that just about anyone can read Jung and come away with a quote 'proving' that Jung agrees with their world view.

1) "Jung's work on himself and his patients convinced him that life has a spiritual purpose beyond material goals. Our main task, he believed, is to discover and fulfill our deep innate potential, much as the acorn contains the potential to become the oak, or the caterpillar to become the butterfly. Based on his study of Christianity, Hinduism, Buddhism, Gnosticism, Taoism, and other traditions, Jung perceived that this journey of transformation, which he called individuation, is at the mystical heart of all religions. It is a journey to meet the self and at the same time to meet the Divine. Unlike Sigmund Freud, Jung thought spiritual experience was essential to our well-being. In 1944 Jung published “Psychology and Alchemy”, where he analyzed the alchemical symbols and showed a direct relationship to the psychoanalytical process. He argued that the alchemical process was the transformation of the impure soul (lead) to perfected soul (gold), and a metaphor for the individuation process."

Freud often chose to disregard the criticisms of those who were skeptical of his theories, however, which earned him the animosity of a number of individuals, the most famous being Carl Jung, who originally supported Freud's ideas. Part of the reason for their fall out was due to Jung's growing commitment to religion and mysticism, which conflicted with Freud's atheism."

"Jung - who unlike a true theist, only reflected on the existence of the afterlife - is barely mentioned in The God Delusion, and his "presence" is hardly an essential part of the book. The point being made could be made without him, using another more suitable example. But where he is mentioned, it gives a false impression I think. Jung did waffle on interminably about religion as if he cared, but he also came out with statements like The wheel may lead our thoughts towards the concept of a "divine" sun, but at this point reason must admit its incompetence; man is unable to define a "divine" being. When, with all our intellectual limitations, we call something "divine", we have merely given it a name, which may be based on a creed, but never on factual evidence. and when discussing the meaning of a dream - The dream is in fact a short summary of my life, more specifically of the development of my mind. I grew up in a house 200 years old, our furniture consisted mostly of pieces about 300 years old, and mentally my hitherto greatest spiritual adventure had been to study the philosophies of Kant and Schopenhauer. The great news of the day was the work of Charles Darwin. Shortly before this, I had been living with the still medieval concepts of my parents, for whom the world and men were still presided over by divine omnipotence and providence. This world had become antiquated and obsolete. My Christian faith had become relative through its encounter with Eastern religions and Greek philosophy. It is for this reason that the ground floor [of the house, his home, in the dream] was so still, dark and obviously uninhabited. - from Approaching the Unconscious, the chapter he wrote in Man and his Symbols, the last book he completed with associates before his death. The word "belief" is a difficult thing for me. I don't believe. I must have a reason for a certain hypothesis. Either I know a thing, and then I know it - I don't need to believe it."
