Yes. The statement in Isaiah 7:14 is taken as a prophecy of the virgin birth of Christ. New Testament passages such as Matthew 1:20, 25, are accepted at face value as declarations of the virgin birth. Christ is accepted as the only begotten Son of God, uniting in his person perfect divinity and perfect manhood.

Isaiah 7:14

Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel.

Matthew 1:20, 25

But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost. And knew her not till she had brought forth her firstborn son: and he called his name Jesus.
