Christadelphians affirm the virgin birth based on Matthew 1:23's explicit citation of Isaiah 7:14, but do not stress the point theologically. Christadelphian exegesis acknowledges that the Hebrew 'almah' can mean 'young woman' as well as 'virgin,' and thus the virgin birth is not necessarily predicted in the Hebrew text. However, the Gospel accounts affirm the miraculous virgin conception, which is accepted as part of apostolic witness. The virgin birth is understood not as proving Christ's pre-existence or divinity but as a sign of God's supernatural work in Jesus' coming.

For Christadelphians, the virgin birth is affirmed but does not carry the same theological weight as it does in Catholic or Eastern Orthodox theology. The focus is on Jesus' exalted status as the Son of God, not on Mariology or the metaphysical implications of the incarnation.
