📖 Biblical Definition
The serpent is Scripture's chief image of Satan and the concentrated evil that tempted humanity into the fall. "Now the serpent was more crafty than any other beast of the field" (Gen 3:1). From the first verses the Bible identifies the tempter as a serpent, and by Revelation the identification is explicit: "that ancient serpent, who is called the devil and Satan" (Rev 12:9, 20:2). The first gospel promise is serpent-crushing: "he shall bruise your head, and you shall bruise his heel" (Gen 3:15, the protoevangelium). And yet the bronze serpent lifted on the pole (Num 21) becomes, in Jesus' words, the type of His own crucifixion: "As Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up" (John 3:14). The venomous symbol of the curse becomes the icon of the cure — because Christ on the cross became the curse Himself (Gal 3:13).
📜 Webster 1828 Definition
SER'PENT, n.
expand to see more
SER'PENT, n. [L. serpens.] Any reptile of the order Serpentes (or Ophidia); a creeping animal without legs, characterized by a long, cylindrical body. In Scripture, the serpent is the first and most enduring emblem of the tempter, who, under this form, deceived our first parents, and was cursed to crawl on his belly and eat dust. The bronze serpent raised by Moses in the wilderness (Num. 21) was a type of the Son of Man lifted up on the cross, by looking unto whom the dying sinner is healed. The great dragon and ancient serpent of Revelation is the devil and Satan, whose head is bruised by the Seed of the woman.
📖 Key Scripture

John 3:14-15 — "As Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, that whoever believes in him may have eternal life."
Revelation 12:9 — "The great dragon was thrown down, that ancient serpent, who is called the devil and Satan, the deceiver of the whole world."
⚠️ Modern Corruption
Modern Christians often treat Satan as a joke or a metaphor; Scripture insists on a real, crafty, personal serpent whose head is being crushed.

Screwtape's first tactic, per C. S. Lewis, was to convince people he did not exist. Modern Christianity is saturated with this success — polls routinely show large percentages of churchgoers treating Satan as "a symbol of evil" rather than a personal being. Scripture is uncompromising: a crafty serpent deceived our first parents, a great dragon wars against the saints, an ancient serpent is thrown into the lake of fire at the consummation. The serpent is real, personal, strategic, and defeated. Recover two truths. First, a real enemy means real spiritual warfare; second, a defeated enemy means certain victory. Christ's heel was bruised at the cross; the serpent's head was crushed in the same blow. You fight from the posture of an already-won war.
