Egyptian myth is the foundation of the trinity
The trinity is based in metaphysics
As Christians, we had reverence for the trinity. The idea comes from the Egyptian roots of Christianity. The meme is a personification of nature.
In modern terms, we would say it is personification of universal laws. Auset would equate to our idea of "mother nature." Ausar would be "father time." he is the principle of the cycle of death, birth, and regeneration personified.
From this myth comes Christian ideas of resurrection, the Virgin birth, Christ, the son/sun of God, salvation, the lamb of God, the Good Shepard, the only begotten son, and many many more.
A look at Etymological origin of the names would uncover many biblical stories. The trinity has a science behind it.
