Mary is a HUMAN. Humans are sinners Mary was a sinner.
Mary was (do we have to PROVE it?) a human.
The BIBLE (which Rome assembled and compiled) says that ALL have sinned and come short of the Glory of GOD. (Do I have to PROVE it?)
Now, somehow, Rome has influenced it's minions that Mary is; somehow; NOT a sinner.
Go figger...
Dumb argument.
Jesus Christ was also a human. After all, he died for our sins.
Jesus Christ was not a sinner.
Why would the Son of God be born of a sinner? Do you believe in original sin? And how it is passed on?
