A second objection
to Mary's virginity arises from the use of the word, heos, in Matthew's gospel.
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.
