I couldn't find in the Bible the words of Elijah that were paraphrased in that book about him. Someone else may find them and quote them from the Bible. However, the prophet Isaiah wrote many warnings to God's chosen people in his day, warning of God's utter condemnation of idols, and idolaters, e.g.:
"Their land also is full of silver and gold, neither is there any end
of their treasures; ...Their land is also full of idols; they worship
the work of their own hands, that which their own fingers have made;
and the mean man boweth down, and the great man humbleth himself [bows
down]: therefore forgive them not. Enter into the rock, and hide thee
in the dust, for the fear of the Lord, and for the glory of his
majesty... And the idols he shall utterly abolish... In that day a man
shall cast his idols of silver, and his idols of gold, which they made
each one for himself to worship, to the moles and to the bats, to go
into the clefts of the rocks, and into the tops of the ragged rocks,
for fear of the Lord, and for the glory of his majesty, when he
ariseth to shake terribly the earth." Isaiah 2:7-21 A.V.
Now, that warning is not restricted to Old Testament times, for it links in to the future prophecies in the book of the Revelation. Read ch. 6 vss. 15-19. That is yet to happen, so the principle applies at all times, to all peoples. Isaiah gives God's warnings many time, also here:
"They lavish gold out of the bag, and weigh silver in the balance and
hire a goldsmith; and he maketh it a god: and they fall down, yea,
they worship. They bear him upon the shoulder, they carry him, and
set him in his place, and he standeth; from his place shall he not
remove: yea, one shall cry unto him, yet can he not answer, nor save
him out of his trouble." Isaiah 46:1-7
Nor does it matter what material is used to make such idols. Concrete was not known to the Old Testament peoples. But elsewhere wood is ridiculed by Isaiah as another material, for part of the wood is used to make a fire, and the rest is carved into an idol, a god, a graven image to whom the person prays, expecting deliverance for so doing (Isaiah 44:13-17). Stone is also a material that idolaters use to make images of that in which they trust to be saved. The prophet Ezekiel also warned of setting up an idol in one's heart - see Ezekiel 14:3-8. In case anyone objects that these are not images of God (who forbids any attempt at making a likeness of himself), they are God to their worshippers; they put those idols before (or, in place of, or equal to) the one, true God.
So comes the point about making any likeness of Jesus Christ, the Son of God who is God incarnate in mainstream Christianity. No photographs could be taken of him while he was on Earth, so all paintings and images and icons are but artistic impressions. Significantly, the Old Testament prophecy of Isaiah says that there was nothing about Messiah's appearance that would attract people to him:
"For he shall grow up before him as a tender plant, and as a root out
of a dry ground; he hath no form nor comeliness; and when we shall see
him, there is no beauty that we should desire him." Isaiah 53:2 A.V.
That, in itself, shows up the folly of artistic impressions of Jesus Christ. As for monuments made, to be looked up to as representing Christ, that invites idolatry, for one can hold that image in one's heart as something to be appealed to, to deliver or comfort. That would be idolatry. Nor is it sufficient to try to distinguish between idolatry as worship, and a secondary kind of 'respect' that is not worship. Going by what the Bible says, worshippers of the only true God would want to keep as far away from risking idolatry, rather than see how close they can get to it without actually 'crossing the line'. I am one from the Reformed tradition, who considers all icons and images to be unacceptable to God.
