Virgin birth- christiansquoting.org.uk

I do not wish to imply that God the Son could not, absolutely speaking, have become incarnate by a non-virginal conception, any more than I should wish to deny that God might, absolutely speaking, have redeemed mankind without becoming incarnate at all; it is always unwise to place limits to the power of God. What we can see is that both an incarnation and a virginal conception were thoroughly appropriate to the needs and circumstances of the case and were more "natural", in the sense of more appropriate, than the alternatives... In practice, denial of the virginal conception or inability to see its relevance almost always goes with an inadequate understanding of the Incarnation and of the Christian religion in general.
