It seems that posters are talking past each other on here because of a central disagreement. Some believe that a living human can communicate with a biologically dead but spiritually alive human. Therefore, they believe that they can communicate with Mary, saints, relatives, or any believer, including asking these biologically dead believers to pray for them. Others, including myself, don't believe in communicating with biologically dead humans despite the fact that we believe each biologically dead believer's soul is spiritually alive.
