OK, you seem to be very confused, let me explain this to you. Read slowly and carefully. Ready? Jesus is God, and we are told to pray to God and send Him our requests. Your saints and Mary are not gods, are they? Now did you get that? Yes we have a two way relationship with God, and it is necessary, but He doesn't speak to me or us audibly, because He doesn't chose to, it requires faith. You do understand what faith is, don't you? And in whom are we to have that faith? It isn't Mary or the saints or any church.
May I edit just a little:) God does speak to us. His Word. That is what the bible is, God speaking to us. We pray to him and he talks to us in his word. He tells us everything we NEED to know to live for him in his word, any thing else is probably of this world and we should steer clear of.
