Note 63 — Chapter IV · BIRTH AND EARLIEST EVENTS OF THE LIFE OF JESUS.

The magi leave Jerusalem by night, the favourite time for travelling in the east. The star, which they seem to have lost sight of since their departure from home, again appears and goes before them on the road to Bethlehem, until at length it remains stationary over the house that contains the wondrous child and its parents. The way from Jerusalem to Bethlehem lies southward; now the true path of erratic stars is either from west to east, as that of the planets and of some comets, or from east to west, as that of other comets; the orbits of many comets do indeed tend from north to south, but the true motion of all these bodies is so greatly surpassed by their apparent motion from east to west produced by the rotation of the earth on its axis, that it is imperceptible except at considerable intervals. Even the diurnal movement of the heavenly bodies, however, is less obvious on a short journey than the merely optical one, arising from the observer’s own change of place, in consequence of which a star that he sees before him seems, as long as he moves forward, to pass on in the same direction through infinite space; it cannot therefore stand still over a particular house and thus induce a traveller to halt there also; on the contrary, the traveller himself must halt before the star will appear stationary. The star of the magi could not then be an ordinary, natural star, but must have been one created by God for that particular exigency, and impressed by him with a peculiar law of motion and rest.63 Again, this could not have been a true star, moving among the systems of our firmament, for such an one, however impelled and arrested, could never, according to optical laws, appear to pause over a particular house. It must therefore have been something lower, hovering over the earth’s surface; hence some of the Fathers and apocryphal writers64 supposed it to have been an angel, which, doubtless, might fly before the magi in the form of a star, and take its station at a moderate height above the house of Mary in Bethlehem; more modern theologians have conjectured that the phenomenon was a meteor.65 Both these explanations are opposed to the text of Matthew: the former, because it is out of keeping with the style of our Gospels to designate anything purely supernatural, such as an angelic appearance, by an expression that implies a merely natural object, as ἀστὴρ (a star); the latter, because a mere meteor would not last for so long a time as must have elapsed between the departure of the magi from their remote home and their arrival in Bethlehem. Perhaps, however, it will be contended that God created one meteor for the first monition, and another for the second.
