Blind leading another blind both will fall in the ditch. This is just my opinion and not a judgmental expressions because God knows my heart. You give yourself some title prayer warrior when your life is a mess itself. This should be an opportunity to help this gentleman and witness with him and share with him the gospel of Jesus Christ. Oh, he knows Jesus because he is catholic, yes, but the difference is catholic also pray to statues, saints, and Mary instead of praying directly to God the Father. He needs salvation and have a personal relationship and fellowship with the Father through Jesus Christ then I guarantee that he will have peace regarding what's going on in front of him. God bless.
