What is the Catholic Church's view of Anne Catherine Emmerich - can her visions and prophecies be trusted? What is the Catholic Church's view of Anne Catherine Emmerich - can her visions and prophecies be trusted? Is she a true prophet by the biblical standard? 

(This question has been prompted by the comments to the answer to What did the serpent look like?)
Please see the link below. In a nutshell, at present the Church distinguishes between the writings attributed to her (which the Church acknowledges may have been done by someone else who then put Emerich's name to those writings) and Emerich herself, her life being one of extraordinary virtue (hence her beatification as a blessed).

At any rate, the Church holds that private revelations, such as those that have been attributed to Emerich, are never binding on Catholics and do not add to the Deposit of Faith in Scripture.
