The question was posed on the title of the thread:
What do you think of the virgin birth of Jesus ?
Baha'is accept the virgin birth of Jesus...
"First regarding the birth of Jesus Christ. In the light of what Bahá'u'lláh and 'Abdu'l-Bahá have stated concerning this subject it is evident that Jesus came into this world through the direct intervention of the Holy Spirit, and that consequently His birth was quite miraculous. This is an established fact, and the friends need not feel at all surprised, as the belief in the possibility of miracles has never been rejected in the Teachings. Their importance, however, has been minimized."
