One thing that we often see is the endless iconography of Christ as Dove. Why?
Christ carries the staff of Aaron. From the time of Moses. But go back further to the time of Noah. The Chi Ro depicts the alignment of the galactic plane with our planetary plane indicating a position in our 26,000 year precession cycle. Some theorize that at the end of this cycle - the dawn of the age of aquarius - earth has large earthquakes and floods - aka time of Noah.
When the flood recedes, we see the dove carrying a sprig of green, a sign that the earth has survived and that the flood is over.
In Genesis 8:8—12, after the ark has landed on the mountains of Ararat,
Noah sends out a dove three times to see how far the flood waters have
receded. The first time it found nothing and returned to the ark. The
second time it brought back an olive leaf, so Noah could see that God’s
punishment was over and life had begun again on the earth. (The image of
a dove holding an olive branch continues to be a symbol of peace to
this day.) The third time, the dove did not return, and Noah knew that
it was safe to leave the ark
and also the baptism of Yashua
came up out of the water, the [Holy] Spirit [of God] came from heaven
and descended on him “like a dove” (see Matthew 3:16; Mark 1:10; Luke
3:22; John 1:32
It was while all the people were being baptized that Jesus was baptized
too, and stood there praying. Suddenly heaven was opened, 22 and
the Holy Spirit came down upon him in bodily form, like a dove, and a
voice came from heaven, which said, Thou art my beloved Son, in thee I
am well pleased.
