There are 3 verses in scripture that speak of God as the consuming fire. Each time refer. God's anger being pushed by the ignorance of man.
The first Deu 9:3 is the tribe of Anakins which were known as the tribe of "Giants" those born of woman by the falling angels = sons of god.
Genesis 6:4 There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare [children] to them, the same [became] mighty men which [were] of old, men of renown.
God was brought to show His anger upon them, and did away with those Anakins that were with the children of Israel.
Deu 9:3 Understand therefore this day, that the LORD thy God [is] he which goeth over before thee; [as] a consuming fire he shall destroy them, and he shall bring them down before thy face: so shalt thou drive them out, and destroy them quickly, as the LORD hath said unto thee.
Jos 11:22 There was none of the Anakims left in the land of the children of Israel: only in Gaza, in Gath, and in Ashdod, there remained.
2. The second time again God finds evil being done, and He again is refer as the consuming fire in Due 4:24
Deu 4:24 For the LORD thy God is a consuming fire, even a jealous God.
Deu 4:25 When thou shalt beget children, and children's children, and ye shall have remained long in the land, and shall corrupt [yourselves], and make a graven image, [or] the likeness of any [thing], and shall do evil in the sight of the LORD thy God, to provoke him to anger:
3. The third time is a warning us not to anger God, but to serve Him with love, as He love us.
Hebrews 12:28 Wherefore we receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear:
Hebrews 12:29 For our God is a consuming fire.
So heed the warning God is a consuming fire. And God hates lies.
There is no 2nd Saviour in scripture.. no church should claim differently.
Christ is our Saviour
