“As a natural phenomenon the virgin birth is unbelievable; only as a miracle, only when its profound meaning is recognized, can it be accepted as a fact.” (J. G. Machen, The Virgin Birth of Christ, pp. 217–218).

“While Matthew presents the quotation [Isaiah 7:14] as his own editorial comment rather than as part of the angel’s message to Joseph, he expects his reader to incorporate this scriptural authentication for Mary’s unique experience into their understanding of why Joseph changed his mind.” (R. T. France, The Gospel of Matthew, p. 48).

“Christ saves, he delivers us from sins. This deliverance consists of two parts. Having made a complete atonement, he brings us a free pardon, which delivers us from condemnation to death, and reconciles us to God. Again, by the sanctifying influences of his Spirit, he frees us from the tyranny of Satan, that we may live ‘unto righteousness,’ (2 Peter 2:24).” (John Calvin, Commentary on the Gospels at Matthew 1:21).
