Must one believe in the Virgin Birth to be a Christian? This is not a hard question to answer. It is conceivable that someone might come to Christ and trust Christ as Savior without yet learning that the Bible teaches that Jesus was born of a virgin. A new believer is not yet aware of the full structure of Christian truth. The real question is this: Can a Christian, once aware of the Bible’s teaching, reject the Virgin Birth? The answer must be no.
