What is the official status of the person of Philomena who at one time was liturgically canonized by Pope Gregory XVI?

**What is the official status of the person of Philomena who at one time was *“liturgically canonized”* by Pope Gregory XVI and not officially canonized?** What are the physical, archeological and scientific historical supports that the Vatican used to suppress her status as a saint in 1961? She was never officially canonized by the Church. > 33.

In order to limit this question to a more historical nature, I prefer that personal opinions be limited to the interpretation of historical data. I also do not desire to have what any visionaries or Catholic mystics have said about the life of [St.] Philomena. Visions are not considered historical proofs. This is exactly how Rome approached the investigation into the beatification of Blessed Catherine Emmerich . > At the time of the Emmerich's beatification in 2004, the Vatican position on the authenticity of the Brentano books was elucidated by priest Peter Gumpel, who was involved in the study of the issues for the Congregation for the Causes of the Saints: "It is absolutely not certain that she ever wrote this. There is a serious problem of authenticity". According to Gumpel, the writings attributed to Emmerich were "absolutely discarded" by the Vatican as part of her beatification process. Thus my question could be phrased as such: **What are the historical reasons that lead up to the Vatican’s decision to suppress the cult of [St.] Philomena and is her cult still permitted in our days?**
