Letters to the author of the discourse of the grounds and reasons of the Christian religion : Shewing, that Christianity is supported by facts well attested; that the words in Isaiah Chap. vii. 14. behold a virgin shall conceive, and bear a son, in their literal and only sense, are a prophecy of the conception and birth of the Messias, fulfill'd in Jesus; and that the Gospel application of several other passages in the Old Testament is just.
