How Satan Interfered with God's Plan
You cannot prove that Christ Jesus is God, although you may believe it.
But most importantly Christ Jesus never said to call Him God.
If Satan wanted to disrupt God's plan to send His Son to the human world and save the world, Satan might try to have people call Christ Jesus God, which was not intended by God.
There must have been a big difference in the human history and especially the European and the Middle East history between the case that people call Christ Jesus God and another case that people don't call Christ Jesus God.
The biggest mystery of the Vatican lies in why they insist on the creed that Christ Jesus is God.
However it should be noted that Christ Jesus might be truly God but God might truly not want people to call Christ Jesus God so as not to give any chance for Satan to interfere with His divine plan.
