There are two
views about how Adam’s sin passed from Adam to the rest of humanity: federal headship and seminal headship. Federal headship views Adam as representing
humanity as its head, thus what he did affected humanity.
In contrast, seminal headship believes that sin is passed through seminally, through the act
of procreation. Some adherents argue that all of humanity was technically in
Adam’s semen, which is why all were affected. However, given the theological
complications of that view, the more accepted view is that sin is somehow passed
along through genetics.
The difficulty
with seminal headship is that Paul’s argument in Romans 5 contrasts Adam and
Jesus as two categories of people. Through Adam comes death, but through Jesus
comes life. The problem is that while all of humanity shares genetic heritage from
Adam, the same cannot be said of Jesus, thus making Paul’s explanation of how
Jesus saves inconsistent with how we inherit salvation. However, seminal headship proponents would argue that Paul’s point isn’t the mechanism of transmission
but the consequence of being in either.
Regardless of one’s
view, the point is the same: Adam’s sin plunged humanity into sin and death.
Left to ourselves, we had no hope. However, in Jesus, we find forgiveness and
eternal life.
Seminal (and federal) headship adherents try to explain the technical process for how
God’s judgment of corruption and death spread to all humanity. Regardless of
one’s view, the point is the same: Adam’s sin is why we are all born sinful
(Psalm 51:5) and God’s enemies (Romans 5:10).
However, though
we indeed inherit original sin, it’s not that we ourselves are
blameless and condemned only because of Adam’s sin. Rather, “all have sinned
and fall short of the glory of God” (Romans 3:23). Thus, we have no grounds to call
God unfair or to blame Adam. Had we been in Adam’s place, we also would have
sinned. Therefore, rather than looking for a way to blame others for sin, we
are all commanded to repent (Acts 17:30).
God, knowing that
we were incapable of pleasing Him and unable to save ourselves, sent His Son,
Jesus, to die. Though eternally divine (John 1:1), Jesus added a human nature
(Philippians 2:6–7) to be born and live like us but without sin (Hebrews 4:15).
He came with the mission of dying as God’s sacrifice for sin (Hebrews 10:12) so
that through His life, death, and resurrection, one way could be made (John
14:6) whereby we could avoid God’s just condemnation (Romans 5:9).
That way is
through our faith in Jesus (Romans 4:5). It is our faith in Jesus that pleases
God (Hebrews 11:6) and through which He justifies us (Romans 5:1) and calls us
His children (John 1:12). To everyone who believes, He removes the sentence of
death we received through Adam giving us the gift of eternal life through Jesus
(Romans 5:17–19).
