While Jonathan C. Sheppard’s book, The Sola Scriptura of Roman Catholicism: Uncovering Rome's Doctrinal Selectivity is rather flawed, it does have some good “counters” to popular-level Roman Catholic apologetics here and there. One such example is his discussion of the popular Roman Catholic appeal to Gen 3:15 to support the personal sinlessness and Immaculate Conception of Mary:
First and foremost, the “woman”
in the text is Eve, the actual person standing before God in the garden. There
is no indication in the passage that it refers to anyone else. The prophecy is
that one of her descendants, her “Seed,” would crush the serpent’s head. The
text does not predict that a future woman would give birth to a seed; it
explicitly identifies the seed as Eve’s own descendant, which Protestants
understand to be ultimately fulfilled in Christ many generations later.
Significantly, the text shifts to the singular masculine, “He shall bruise your
head,” pointing to an individual male descendant, not to the woman herself. The
focus is on her offspring, not on Mary’s moral condition.
Even if Mary is seen as a
typological fulfillment of the “woman,” that typology does not require
sinlessness. In fact, biblical typology often uses imperfect people to
foreshadow something greater. David, for example, foreshadowed the coming
Messiah through his God-given role as king, yet he was far from sinless. The
nation of Israel foreshadowed the Church, yet frequently fell into
disobedience. Eve was created without sin and fell, and Mary, though sharing in
the fallen condition of humanity, was faithful and obedient in fulfilling her
role in God’s redemptive plan. There is no need to insist that a typological
parallel requires moral or ontological equivalence.
Moreover, the idea that perfect
enmity must imply complete moral separation from sin has no textual support.
God declares enmity not only between the serpent and the woman, but also
between their seeds, meaning this enmity applies to generations of people, many
of whom were obviously sinful. Scripture speaks often of God’s enmity with the
wicked or between spiritual forces, but these statements do not demand sinless
perfection to be meaningful. Mary’s role in opposing Satan, by faithfully
submitting to God’s plan, does not require her to be sinless any more than the
prophets or apostles needed to be sinless to carry out their God-given
missions.
In conclusion, the attempt to
insert Mary’s sinlessness into this verse reflects what we’ve already seen in
Luke 1:28: a doctrine looking for a prooftext. The passage nowhere addresses
Mary, her conception, her spiritual condition, or her relationship to original
sin. It speaks of Christ, the woman’s descendant, who will defeat Satan, not
the woman herself. To build a major dogma like the Immaculate Conception on
such a distant and indirect reference is not only theologically unsound; it’s
an example of reading Church tradition into the text, rather than drawing
doctrine from it. (Jonathan C. Sheppard, The Sola Scriptura of Roman
