The belief that Satan is responsible for the sins of mankind, as the author of human sin, is not supported by God's word. While Satan deceives and influences through his attitudes and broadcasts, God's word does not teach that mankind's sins belong on his head. Ephesians 2:2 acknowledges a spirit influence at work, but the spirit in man, which enables free moral agency, means that an outside spirit does not force actions, only provides material for decisions. God declares that mankind is without excuse, as seen in the choices set before ancient Israel to choose life or death, showing that responsibility lies with the individual. James 1 explains that sin arises from personal desires, not from Satan's authorship, highlighting that the issue is the human heart, not external forces. John 8:44 identifies Satan as a spiritual father to some, teaching murder and lies, but Ezekiel 18:19-20 clarifies that each soul is accountable for its own sins, not those of a father, spiritual or otherwise. God holds individuals responsible, expecting them to recognize and reject sinful influences. I John 3:8-9 contrasts sinning as a way of life with being born of God, indicating alignment with Satan through consistent wrong choices, not authorship of sin. Genesis 3:17 attributes Adam's sin to heeding another's voice, yet God does not accept blame-shifting, as seen with Adam and Eve. Romans 5:12 states sin entered through Adam, not Satan, emphasizing human accountability, while Romans 7 shows Paul's struggle with indwelling sin, with no blame placed on Satan. God's word rejects the notion of divided guilt or partial sin. Leviticus 5:17 affirms that a person bears full iniquity for sin, even in ignorance or deception. There is no biblical concept of a co-sinner or split penalty; each sin earns the full death penalty for the sinner. The idea that Christ paid only for mankind's part of sin, leaving Satan's part unatoned, contradicts the need for full acknowledgment of guilt in repentance, as seen in Psalm 51. Each man's sins are his own, and Satan's sins are his own, with no fractional penalty. The danger lies not in Satan making mankind sin, but in individuals choosing to sin and incurring the death penalty, often influenced by faulty reasoning. God's admonitions to resist deception and draw near to Him underscore personal accountability for these choices. The assertion that Leviticus 16 symbolizes Satan's sins being placed on his head is incorrect, as the passage specifies the iniquities of the children of Israel on the goat of departure, not Satan's sins. Relying on traditions outside God's word for such beliefs risks undermining its truth.
