Codd. Roe, Casaub. have a different reading—“Think not then of His having now been born in Bethlehem, and (nor) suppose Him as the Son of Man to be altogether recent, but worship, &c.”  This is rightly regarded by the Benedictine and other Editors as an interpolation intended to avoid the apparent tendency of Cyril’s language in the received text to separate the Virgin’s Son from the Eternal Word.  Had Cyril so written after the Nestorian controversy arose, he would have appeared to favour the Nestorian formula that “Mary did not give birth to the Deity.”  Compare Swainson (Nicene Creed, Ch. ix. § 7.)  What Cyril really means is that we are not to think of Christ simply as man, but to worship Him as God.
