Here in the Wiki states the Primordial God "Yuanshi Tianzu":
"Taoists claim that sacrifices offered to Yuanshi Tianzun by the king predate the Xia dynasty. The surviving archaeological record shows that by the Shang dynasty, the shoulder blades of sacrificed oxen were used to send questions or communication through fire and smoke to the divine realm, a practice known as scapulimancy. The heat would cause the bones to crack and royal diviners would interpret the marks as Yuanshi Tianzun's response to the king. Inscriptions used for divination were buried into special orderly pits while those that were for practice or records were buried in common middens after use."
"Under Yuanshi Tianzun or his later names, the deity received sacrifices from the ruler of China in every Chinese dynasty annually at a great Temple of Heaven in the imperial capital. Following the principles of Chinese geomancy, this would always be located in the southern quarter of the city. During the ritual, a completely healthy bull would be slaughtered and presented as an animal sacrifice to Yuanshi Tianzun. The Book of Rites states the sacrifice should occur on the "longest day" on a round-mound altar. The altar would have three tiers: the highest for Yuanshi Tianzun and the Son of Heaven; the second-highest for the sun and moon; and the lowest for the natural gods such as the stars, clouds, rain, wind, and thunder. The ten stages of the ritual were:
Offering of jade and silk Offering of sacrificial food
First offering of wine
Second offering of wine
Last offering of wine
Retreat of civil dancers and entry of military dancers
Performance of the military dance
Farewell to deities
Burning of sacrificial articles
"It is important to note that Yuanshi Tianzun is never represented with either images or idols. Instead, in the center building of the Temple of Heaven, in a structure called the "Imperial Vault of Heaven", a "spirit tablet" (神位, or shénwèi) inscribed with the name of Yuanshi Tianzun is stored on the throne, Huangtian Shangdi (皇天上帝). During an annual sacrifice, the emperor would carry these tablets to the north part of the Temple of Heaven, a place called the "Prayer Hall For Good Harvests", and place them on that throne."
This is further explained in "Truth about Shang-di" chapter, as "Shang-di" is somewhat different than the one called "Yuanshi Tianzun". However, Shang-di and Yunashi Tianzun are shown or portrayed with an image, but from the above statement states that Yuanshi Tianzun is "not" supposed to have an image, and is supposed to be "His name" inscripted on the spiritual Tablet in the Temple of Heaven.
Here are scriptures detailing the name of God: 2 Samuel 7:13 "He shall build an house for my name, and I will stablish the throne of his kingdom for ever."
1 Kings 5:5 "And, behold, I purpose to build an house unto the name of the LORD my God, as the LORD spake unto David my father, saying, Thy son, whom I will set upon thy throne in thy room, he shall build an house unto my name."
1 Kings 8:16 "Since the day that I brought forth my people Israel out of Egypt, I chose no city out of all the tribes of Israel to build an house, that my name might be therein; but I chose David to be over my people Israel."
1 Kings 8:18 "And the LORD said unto David my father, Whereas it was in thine heart to build an house unto my name, thou didst well that it was in thine heart."
1 Kings 8:19 "Nevertheless thou shalt not build the house; but thy son that shall come forth out of thy loins, he shall build the house unto my name."
1 Chronicles 22:8 "But the word of the LORD came to me, saying, Thou hast shed blood abundantly, and hast made great wars: thou shalt not build an house unto my name, because thou hast shed much blood upon the earth in my sight."
1 Chronicles 22:10 "He shall build an house for my name; and he shall be my son, and I will be his father; and I will establish the throne of his kingdom over Israel for ever."
2 Chronicles 6:6 "But I have chosen Jerusalem, that my name might be there; and have chosen David to be over my people Israel." 2 Chronicles 6:8 "But the LORD said to David my father, Forasmuch as it was in thine heart to build an house for my name, thou didst well in that it was in thine heart:"
Deuteronomy Chapter 12 :"1These are the statutes and judgments, which ye shall observe to do in the land, which the LORD God of thy fathers giveth thee to possess it, all the days that ye live upon the earth. 2Ye shall utterly destroy all the places, wherein the nations which ye shall possess served their gods, upon the high mountains, and upon the hills, and under every green tree: 3And ye shall overthrow their altars, and break their pillars, and burn their groves with fire; and ye shall hew down the graven images of their gods, and destroy the names of them out of that place. 4Ye shall not do so unto the LORD your God. 5But unto the place which the LORD your God shall choose out of all your tribes to put his name there, even unto his habitation shall ye seek, and thither thou shalt come:"
He clearly states that "His" name should be put there and that no image should be portrayed. This "House", in which is supposed to be in Jerusalem, has to be the Temple of Heaven that is located in Beijing, China. So, if Hebrews 12:29 and Deuteronomy 4:24 states "Our God is a consuming fire" and a "jealous God", only tells me that the Isrealites was supposed to blot out the name of the former deities in those lands, and put "His" name there instead, thus is towards the God of fire.
