he Anglican Communion, Eastern Orthodoxy, Protestantism and Roman Catholicism have taught the "virgin birth," although the term "virgin conception" would be much more accurate. This has long been one of the Christianity's foundational beliefs, along with the inerrancy of the Bible; the God's inspiration of the authors of the Bible; the atonement, resurrection, and the anticipated second coming of Jesus, etc. All of the commonly used major ancient church creeds have also mentioned the virgin birth.
Most modern liberal theologians have generally rejected the virgin birth. They regard it as a religious myth that was added to Christian belief in the late first century CE and was triggered by a Greek mistranslation of the book of Isaiah from the original Hebrew. Its purpose was to make Christianity more competitive with contemporary Pagan religions in the Mediterranean region, most of whom featured their founder having being born of a virgin. Without the claim of a virgin birth, it is unclear whether Christianity could have survived.
Various polls have found that about 80% of American adults believe in the virgin birth of Jesus. This exceeds the total number of American adults who identify themselves as Christian or Muslim. In fact, 47% of non-Christian adults also believe in the virgin birth.
