Surah of the Sacred Sincest

The one she chose to impregnate her was none other than her own father...

"Oh Saintess, sacred thou. For the sake of confronting the demon lord, I call upon thee to conceive a child with thy dearest beloved."
On that day, I, the daughter of a lone priest, received my calling as the Saintess. My body was bestowed with un-aging youth and beauty and a power worthy of God. Many witnessed the divine oracle's proclamation that day, so none could doubt it.
Being a smart girl with but a very strange mind, I felt a little nervous, but it was a terribly joyous occasion for me.
The saintess raises heroes, for she is the life-giving womb... Indeed, God recognizes her as the most immaculate womb in this world. And I, I am a strange girl who rejoiced at such a duty, so perhaps this is why I was left with such a warning.
"...Thoust holds love too deep. Even I may not stop it. Beware not to let it stray too far."
I know that already. I intend to respect my beloved's wishes, after all.
"Good morning... Father."
And it is he, who was but a low-ranking priest, who is my dearest beloved.
The one who sired this now flawless womb- my father.
