The revealing of Jesus as a member of the eternal Godhead occurred when Mary arrived at the sepulcher immediately after the resurrection. I say this because of the facts given below:
When the Ark of the Tabernacle was being built, Yahweh instructed Moses to build the Mercy Seat as follows:
17 “Make an atonement cover of pure gold—two and a half cubits long and a cubit and a half wide. 18 And make two cherubim out of hammered gold at the ends of the cover. 19 Make one cherub on one end and the second cherub on the other; make the cherubim of one piece with the cover, at the two ends. 20The cherubim are to have their wings spread upward, overshadowing the cover with them. The cherubim are to face each other, looking toward the cover. 21Place the cover on top of the ark and put in the ark the tablets of the covenant law that I will give you. 22There, above the cover between the two cherubim that are over the ark of the covenant law, I will meet with you and give you all my commands for the Israelites. Exodus 25
Mary went to the sepulchre where Jesus body had been placed and looked inside. She found the body of Jesus missing:
And she saw two angels in white, sitting where the body of Jesus had lain, one at the head and one at the feet. John:20:12
In the Ark of the Tabernacle, two Cherub and been placed at each end of the place where the covenant of law was placed. Now two angels sat, one at the head and one at the feet where Jesus lay. Jesus has replaced the old covenant and written in His own blood the New Covenant, so fulfilling the scriptures as we are told:
“The days are coming, declares the LORD,
when I will make a new covenant
with the people of Israel
and with the people of Judah.
9It will not be like the covenant
I made with their ancestors
when I took them by the hand
to lead them out of Egypt,
because they did not remain faithful to My covenant,
and I turned away from them,
declares the LORD.
10This is the covenant I will establish with the people of Israel
after that time, declares the Lord.
I will put My laws in their minds
and write them on their hearts.
I will be their God,
and they will be My people.
11No longer will they teach their neighbor,
or say to one another, ‘Know the LORD,’
because they will all know me,
from the least of them to the greatest.
12For I will forgive their wickedness
and will remember their sins no more.”
13By calling this covenant “new,” He has made the first one obsolete; and what is obsolete and outdated will soon disappear.
These events in Judea surrounding Jesus resurrection caused other events. As we read John 20 we see Thomas and Jesus say:
Luke records the words of Peter when he writes of this same Jesus:
And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved. Acts 4:12
