You said: only God the Father, God the Son, and God the Holy Spirit hear..
How do you know? Where in scripture does it say NOBODY else in Heaven can hear prayer? Again, protestants always try to limit what God can do, cause Him to be finite. If God wants to allow saints to hear us He can.
How about showing me in scripture where God says that anyone other than he himself DOES hear prayer? In fact, why not revisit Elijah’s contest with the prophets of Baal. Who did Elijah pray to? Adam? Eve? Seth?
Who did Christ pray to in the Garden of Gesthemene? Moses? Abraham? His mother? No. He prayed to God. God answers prayer, no one else. God hears prayer. He doesn’t say, “I and the certain saints hear prayer, “ or, “I and Mary and the saints hear prayer.”
Show me where God says anyone but himself hears prayer and then you can show me also that someone other than God answers prayer. My bet is you won’t find it.
Your comment on Protestants is rather a broad brush and very non-specific. God IS sovereign. God is sovereign according to HIS will. Not Protestant will or Catholic will. So, why assume that God allows saints to hear and answer prayer when He doesn’t say? But, He DOES say that we are to worship HIM alone; to do otherwise is idolatry. And, to me, praying to anyone or anything other than God is practicing idolatry.
