I would say the Hebrew Bible's Yahweh because he lies at the center of the three major religions in the West and has inspired controversy, literature, countless other works and re-workings, not least of all in the figures of Allah and Christ, who are pretty much reactions to Yahweh and the Hebrew Bible. As the saying goes, Christ hardly sneezes in the Gospels without referencing the Tanakh.
Though while Yahweh may not be as revered as Christ today (though indeed various normative interpretations of him from various books of the OT still live on) he is still, I believe, the backbone of our entire Western religious and even literary identity. All monotheistic representations of God seem to be derived from the J writer's Yahweh, from Milton's watered-down God in Paradise Lost (who is a weak character when compared to the greatly human Satan) to Michelangelo's mighty God swooping out of the clouds in the Sistine Chapel. Even Freud's hyperbole that the Yahweh is the origin of the super-ego in the West, I certainly don't dismiss the similar claim that there has never been a more powerful and omnipresent embodiment of the super-ego in literature.
I would also argue that Yahweh is probably the most enigmatic and strangest character in all of literature. I would be hard-pressed to name any characterization that is more uncanny than J's (the hypothetical writer of the best parts of the Torah). What character has inspired so many readings of this perplexing passage here?:
KJV transQuote:
And the LORD said unto Moses, When thou goest to return into Egypt, see that thou do all those wonders before Pharaoh, which I have put in thine hand: but I will harden his heart, that he shall not let the people go.
22 And thou shalt say unto Pharaoh, Thus saith the LORD, Israel [is] my son, [even] my firstborn:
23 And I say unto thee, Let my son go, that he may serve me: and if thou refuse to let him go, behold, I will slay thy son, [even] thy firstborn.
24 And it came to pass by the way in the inn, that the LORD met him, and sought to kill him.
25 Then Zipporah took a sharp stone, and cut off the foreskin of her son, and cast [it] at his feet, and said, Surely a bloody husband [art] thou to me.
26 So he let him go: then she said, A bloody husband [thou art], because of the circumcision.
Another personal favorite passage of mine and one that has enamoured me for so long is Jacob's wrestling with a strange man who turns out to be Yahweh himself:
Then there is the triumphant meeting between Yahweh and Moses with his priests on the top of Mount Siani which is altogether unlike anything literature has ever offered.Quote:
And he rose up that night, and took his two wives, and his two womenservants, and his eleven sons, and passed over the ford Jabbok. And he took them, and sent them over the brook, and sent over that he had. And Jacob was left alone; and there wrestled a man with him until the breaking of the day. And when he saw that he prevailed not against him, he touched the hollow of his thigh; and the hollow of Jacob's thigh was out of joint, as he wrestled with him. And he said, Let me go, for the day breaketh. And he said, I will not let thee go, except thou bless me. And he said unto him, What is thy name? And he said, Jacob. And he said, Thy name shall be called no more Jacob, but Israel: for as a prince hast thou power with God and with men, and hast prevailed. And Jacob asked him, and said, Tell me, I pray thee, thy name. And he said, Wherefore is it that thou dost ask after my name? And he blessed him there. And Jacob called the name of the place Peniel: for I have seen God face to face, and my life is preserved. And as he passed over Penuel the sun rose upon him, and he halted upon his thigh.Therefore the children of Israel eat not of the sinew which shrank, which is upon the hollow of the thigh, unto this day: because he touched the hollow of Jacob's thigh in the sinew that shrank.
Christ of course is right there along with Yahweh as one of literatures most memorable characters (even though I am personally more moved and awed by the J writer than any of the writers of the Gospels) and I find all of his various representations fascinating, for they are about as diverse as Yahweh's; from the love-thy-neighbor Christ of Matthew to the anti-Semetic Christ of John to the Gnostic and enigmatic Christ of Thomas to the warrior Christ of Revelations.Quote:
9 Then went up Moses, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel:
10 And they saw the God of Israel: and [there was] under his feet as it were a paved work of a sapphire stone, and as it were the body of heaven in [his] clearness.
11 And upon the nobles of the children of Israel he laid not his hand: also they saw God, and did eat and drink.
The so-called "lack of character development" is probably because it's a pre-novel ancient text and was meant as scripture. Also, I don't know what you mean by the "weird" dialouge. Sure the dialouge in the Gospels isn't in modern English dialect (that would be weird if it was), it's made up of sermons, soliloquies, question-and-answer bits, etc.
That said, it is arguable that there may be better "Christ-figures" in literature even than Christ himself. Indeed I am far more moved by Dostoyevsky's Prince Myshkin than even Matthew's immortal depiction. That said, my favorite "Christ-figure/version" is probably the Christ from the non-canonical Gospel of Thomas.
