Scoffing at the Biblical doctrine of “original sin.” “The Big Lie! It’s not your fault, Augustine. You inherited Adam’s sin. God knows it passes from father to child in everyone. Yet He condemns you anyway. I told you he was unjust. But, it’s OK now, He punished someone else for it in your place. Trust me.”

Christian response,

For all intents and purposes, original sin finds its origin in the Kingdom of God before the creation of Time and that sin and its Initiator is causation for the creation of matter, Time, the Universe, this Earth, our human genome, as that sin and Offender were extricated from the Kingdom and placed upon this Earth to be dealt with partially constrained by Time and physics; in fact, the primary reason Jesus Christ left the Eternal Realm and entered the Realm of Time was “to destroy the works of the Devil” (1 John 3:8b) via the Gospel that was ordained “before the beginning of Time” (2 Timothy 1:9-10).

Concerning “original sin” as it relates to Adam and human kind,

The sin-nature, mankind’s natural propensity to reject God’s authority, passes through the seed of the first man, Adam, as Elohim held Adam to greater culpability for Eden in accordance with federal headship and the truism that Adam had received the edict to eschew evil directly from Elohim; whereas, Eve received the directive by hearsay; that is, from her husband, Adam. It is Adam’s seed that infects all of mankind with a corrupted genome, a sin-nature that naturally seeks rebellion to God’s will and His righteousness.

It is written,

11 Not only that, but we also rejoice in God through our Lord Jesus Christ, through whom we have now received reconciliation. 12 Therefore, just as sin entered the world through one man, and death through sin, so also death was passed on to all men, because all sinned. Romans 5:11-12

This is why Messiah, who entered Time to destroy the works of the Devil (1 John 3:8b), was born of the virgin seed of the woman (Genesis 3:15; Matthew 1:26) through the Holy Spirit (Luke 1:35) as this virgin birth permitted the hypostatic union of God and man in flesh (Philippians 2:6-8); it is the hypostatic union that permitted Messiah to exist in Time in sinlessness and fulfill the righteous requirements of the Decalogue and 613-Levitical Laws in absolute perfection thereby becoming the only acceptable atonement for sin (2 Corinthians 5:21). The Covenant of Law demanded perfection in order to attain righteousness through it but mankind’s sin-nature resulted in the Law becoming a curse and condemnation void atonement (James 2:10; Galatians 3:10; Romans 8:3; Romans 3:20); therefore, Jesus kept the Law for us in perfection and defeated death, Hell and the grave at Golgotha. The Gospel of Jesus Christ, ordained before the beginning of Time (2 Timothy 1:9-10), is the Plan of God by which Satan has been defeated through God’s selfless love demonstrated at Golgotha and first pictured in Scripture in Genesis 3:21 and fulfilled 4000-years later at the Crucifixion with the words “It is finished” (John 19:30).

Without the virgin birth of Messiah and the hypostatic union resulting from same, mankind would be destined to death in Hell without hope (John 3:16-18) because Messiah Jesus is the only Way to redemption/forgiveness of sin by faith and Jesus is the only Way to the Father in Eternity (John 14:6); this forgiveness of sin through the blood atonement was essential as God the Father has ordained that “nothing impure” will ever enter His Kingdom (Revelation 21:27).

Concerning original sin and children,

Infants are born into sin through their father’s seed through Adam’s seed (Psalm 51:5) but children are not held accountable or culpable for that sin until such time they attain an age of reason sufficient to discern God’s natural law through the conscience (Romans 2:15). Where there is no law, there is no sin (Romans 4:15; 5:13).

It is written concerning Jesus and children,

13 Then the little children were brought to Jesus for Him to place His hands on them and pray for them. And the disciples rebuked those who brought them. 14 But Jesus said, “Let the little children come to Me, and do not hinder them! For the kingdom of heaven belongs to such as these.” 15 And after He had placed His hands on them, He went on from there.… Matthew 19:13-15 (Berean Study Bible)
