Immaculate Conception - Mariology Resources
Although he does not mention Mary's Immaculate Conception in those words, notice how Prudentius identifies the quarrel between the snake and the man in Genesis 3 with the fall of man into sin and death. He then contrasts this falling of man (whereby man is separated from God and thus corrupted by Original Sin), with the coming of Christ [New Adam] and Mary [New Eve]. Mary herself is not only immune to, but subdues every poison of the Serpent [Satan], and is put in a totally different category than those under Satan's dominion. The logic behind his statement here is clear: Christ as New Adam, and Mary as New Eve, are categorically distinct from those who are under the curse of death and corrupted by the fall of man; Christ and Mary trample on the serpent and the venom is harmless to them [original sin, corruption].
Here is another passage of Prudentius where he identifies the venom of the serpent closely with sin (original and actual):whom Thou lovest and dost not suffer to perish, I am he on whom Thou in thy goodness didst take compassion when I was all defiled with the venom of serpents and stained with many a sin.
