A second objection to Mary's virginity arises from the use of
the word, heos,
in Matthew's gospel.
Matthew 1:25
He (Joseph) had no relations with her until (heos)
she bore a son, and he named him Jesus.
The Greek and the Semitic use of
the word heos (until or
before) does not imply anything
about what happens after
the time indicated. In this
case, there is no necessary implication
that Joseph and Mary had sexual
contact or other children
after Jesus.
