The Egyptian Pharaoh identifies with the dying and rising sun god Re during his baptism.Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life.
For if we have been united with him in a death like his, we will certainly be united with him in a resurrection like his. 6 We know that our old self was crucified with him so that the body of sin might be destroyed, and we might no longer be enslaved to sin. 7 For whoever has died is freed from sin.
Conceptions Of Purity In Egyptian Religion Joachim Friedrich Quack
The Egyptian Book of the Dead: The Book of Going Forth by Day edited by Eva Von DassowThe person of the king was strongly connected to purity concerns in Egypt.46 Indeed, there exists a detailed royal ritual focused on purification rites...
Spell for the water
O Water, may you abolish all bad defilement of the pharaoh,
O inundation, may you wash off his errant demons...
Spell for water, speaking words [by...]
[O you Gods...,
Come] that you [erase] all evil in him.
Any taboo he did, [...] at the lake!...
Another spell for purification, speaking words:
Pharaoh has [purified himself] with the great waters
Which come forth from Elephantine, which originate from the [primeval
ocean]...
Pharaoh is purified with this water which came out from Osiris...
Another spell for purification, words to be spoken.
PHARAOH IS RE, ARISING IN THE PRIMEVAL OCEAN,
[His] purity is [the purity of... in the] water,
With big flame...
Great illuminator when he shows himself in the flood in the morning,
Who abolishes all evil, as he arises in his purity from the flood.
May pharaoh arise in the flood(?)—
...shine... pharaoh...
May he be divine in the earth!
Those who are in the primeval ocean shall not upset him...
The royal ritual has links to the ideal of the sun god, in which, according to the Egyptian conception, the morning purification precedes the
sunrise.
The Complete Gods and Goddesses of Ancient Egypt, Richard H. WilkinsonEvery evening the aged sun entered the underworld and travelled through it, immersed in Nun, only to emerge at dawn as Khepri, the newborn sun. Thus, the waters of Nun had a rejuvenating, baptismal quality essential to rebirth.
Death and Salvation in Ancient Egypt, Jan AssmannThe great sun god Re was thought to grow old each day and to 'die' each night... and then to be born or resurrected
each day at dawn.
Regeneration did not mean traveling a reversed path from death to birth, but rather, being born anew through death...
Every morning, the sun god emerged from the primeval waters, and the annual Nile inundation that renewed the fertility of the land also fed on these netherworldly primeval waters...
"we live again anew,
after we enter the primeval water,
and it has rejuvenated us into one who is young for the first time.
The old man is shed, a new one is made."
