I have received what I believe to be credible information on the identity of the false visionary who calls herself “Maria Divine Mercy”:
5 Muldowney Court
Here is what her voice sounds like from a radio interview.
Her diocese and bishop are:
Archbishop Diarmuid Martin of the Dublin archdiocese.
Her parish is:
St Sylvester’s Church
Malahide, County Dublin, Ireland
If you are concerned about her false messages, I suggest writing to her pastor and her Bishop.
