In ancient Kush/Kemet, "in keeping with the nine inseparable parts of the human soul", a child is not given a name (Ren) until a spiritual ceremony was performed, now called "Baptism" in the Euro-Christian religion.
In Kemetic practice, purification takes two forms, "magical" and physical. The former is done by declaring that you are fit to contact the netjer.
"I, [name,] am a child of Ra. I am a child of the Lord of Life, I am created from the tears of the Eye of Ra. As Ra bathes in the waters of the Lake , so now do I bathe in the waters of the Lake. As Ra I am purified and cleansed. As Ra I am renewed and rejuvenated…
...that I may kiss the earth so great is his majesty, that I may endow his image with life. I am pure. I am purified.”
