>> “You think Catholics communicare with dead bodies??” <<
Childish strawman.
Communicating with the dead, necromancy, is forbidden. Its a serious sin, and a habit that leads straight to the lake of fire. The spirits of the dead are not available for communication, and all attempts are answered by the fallen ones.
Intercessory prayer to the saints does neither of these things: it does not conjure up spirits, and it does not attempt or pretend prophecy/divination. It's not necromancy,and if anyone were to try to use Christian prayer as a form of necromancy, that would be a sin.
Are you a member of a church that teaches that the faithful departed are cut off from the Body of Christ and have no more interest in us or are in no position to pray for us? I would like to understand more of where this view comes from, since I can't seem to find a Christian source. Can you suggest a website that links to your church's teachings?
Second, why don';t you respond to what I asked? Do you believe in the Trinity? In the Communion of Saints? Do you believe we are members of the Body of Christ?
