Augustine of Hippo

Christ was born a visible man of a human virgin mother, but he was a hidden God because God was his Father. So the prophet had foretold: "Behold, the virgin shall be with child and shall bring forth a son; and they shall call his name Emmanuel, which is interpreted, God with us." To prove that he was God, Christ worked many miracles, some of which—as many as seemed necessary to establish his claim—are recorded in the Gospels. Of these miracles the very first was the marvelous manner of his birth; the very last, his ascension into heaven in his body risen from the dead.
