The Christian Halo is symbolic of
divinity and supreme power. Divinity means of, or pertaining to god. The Holy Spirit is god, the third person of the Holy Trinity.
Notice how the supernatural orb looks exactly like this Christian Halo.
I believe that the Christian Halo can be seen in scripture as the Spirit of God alighting upon Jesus.
Mathew 3:16 When He had been baptized, Jesus came up immediately from the water, and behold; the heavens were opened to Him, and He saw the
Spirit of God descending like a dove and
alighting upon Him.
The Spirit of God is the Holy Spirit.
The Spirit of God alighting upon Jesus most likely appeared as a Halo.
