Is it necessary to believe the virgin birth?
People are free to believe whatever they want, and no one needs to be coerced into believing anything. That’s not really how believing works. Being forced to believe something isn’t the same as believing something.
So in that sense it isn’t necessary to believe in the virgin birth.
But if you are committed to believing what the bible says, then it is necessary to believe in the virgin birth. Both Matthew 1 and Luke 1 speak of Mary as a virgin. The creeds of the early church, both the Nicene Creed and the Apostle’s Creed, both speak about the virgin birth. The Nicene Creed says, that Jesus “was incarnate of the Holy Spirit and the Virgin Mary” the Apostle’s Creeds says that Jesus was “born of the Virgin Mary”. And these creed are held to across the various flavours of Christianity, both Eastern and Western Christianity and both Protestant and Roman Catholic. Belief in the Virgin Birth is simply a part of orthodox Christianity.
