I don't know the answer to that one, but Dia's answer sounds right. Retrouvaille describes itself as a Christian Peer Ministry. It is not counseling and it does not employ any professional counselors. So I guess it's equivalent to asking a doctor about herbal cures. As to why a Catholic Deacon is unaware of it, I don't know. He should be. When you get back from Retrouvaille, Orich, be sure to tell him about it. And they will give you brochures that you can give him to give to others.
