"They aren't even allowed to talk (pray) to Jesus, their supposed King."
Nothing to do with being allowed. It's a matter of that's not how it works.
Why would anyone want t pray to Jesus when he said: "“You must pray, then, this way: “‘Our Father in the heavens"
Romans 1:8 "I give thanks to my God through Jesus Christ concerning all of you,"
John 14:6 "Jesus said to him: “I am the way and the truth and the life. No one comes to the Father except through me"
The only thing indicating any form of prayer to Jesus is: John 14:13 "Also, whatever you ask in my name, I will do this, so that the Father may be glorified in connection with the Son. If you ask anything in my name, I will do it"
But that is so narrow and specific it can hardly be consider a prayer.
