An article this author wrote entitled “What did Jung see on the Shroud?” was posted on the Collegamento pro-Sindone website many years ago and has some useful details about what he thought about the relic as well as something on his religious beliefs.

Here is a link to the article in question, What did Jung see in the Shroud?, by Louis C. de Figueiredo

Here is the last paragraph (but do read the entire article, it is worth it):

It is difficult to say with certainty why he kept a copy of the face on the Turin Shroud. Perhaps he intuitively guessed something about the mystery of this extraordinary image that had already been called acheiropoetos, that is “not made by human hands” in Greek, by the Byzantine Christians in the first thousand years of its existence. These Eastern Christians never kept the Shroud permanently exposed. under public gaze, a tradition that was naturally followed by the Catholics. One thing seems certain. Jung believed the image was genuine, in fact told the American writer Upton Sinclair that it had created the strongest impression on him, for the “stern and august countenance” had confirmed his “formerly vague expectations.” He hung the copy of the Shroud face in his study — behind a curtain.
