It is great, but some think that only Jesus and the father are one, not everyone and the father.
It is just the working of the conditioned mind.
In Jesus's time, the rabbis found his words equating himself with divinity as blasphemous and falsely convicted him to get him killed and rid of.
After the Catholic church came up, they created the doctrine that only God and Jesus are divine, and none else. ( contrary to Jesus's teachings).
When
Meister Eckhart , like Jesus, came up with nondualistic teachings of God, the Catholic Church, in great irony, criticized his teachings considering it heretical, and almost did to him what the Rabbis and Romans did to Jesus. His death before the verdict came out saved him from the Inquisition.
The eye with which I see God is the same with which God sees me. My eye and God's eye is one eye, and one sight, and one knowledge, and one love. - Meister Eckhart
All that the Eternal Father teaches and reveals is His being, His nature, and His Godhead, which He manifests to us in His Son, and teaches us that we are also His Son. - Meister Eckhart
