Nothing to worry about if living in a state of grace!
I am contacting you regarding a situation involving a young woman who has reached out to our pastor. She claims that she is possessed by the devil and she is requesting an exorcism and baptism. My pastor met with her and thinks that she may be suffering from some form of mental illness. She seemed desperate to the point of offering to pay a sizable amount of money for the baptism. Our pastor informed her that we do not accept payment for sacraments. His feeling is that she would be unable to commit or profit from RCIA due to her mental state and circumstances. On the other hand, he does not want to deny her the sacrament of baptism out of compassion. He has asked me to reach out to her to get a feel for the situation. Given your experience in such matters I'm asking for your advice in regards to how I might best approach her while making sure that I do not open myself up to the demonic.
I have talked to many demonically possessed people, as long as your in a state of grace you have nothing to worry about. Of course, before you talk to her make sure you do a prayer of protection over yourself like the St Michael the Archangel prayer and the Anima Christi (Soul of Christ). Don't pray over her, don't touch her (obviously), don't be alone with her (have a witness if you meet in person) and don't let her bring you into her world emotionally or psychologically. If your Pastor has already determined that she would not profit from RCIA because of her mental condition than you should refer her to a Catholic therapist or Counselor before you proceed to bring her into RCIA. Let an expert determine is she is mentally fit or if their is something else at play here.
