Christ Jesus taught to pray to the Father, who is in Heaven.
'The meaning of "to pray" is "to ask".
Asking (praying) any other entity in Heaven to intercede is disobeying Christ, and opening one to demonic activity.
Even the Saints in the Scriptures to whom angels from Heaven were sent, did not themselves invoke those angels, never. The angels were sent by God. God was deciding to whom He would have His angels speak.
