John Chrysostom

As He had above described in what guise Antichrist should come, so here He describes how He Himself shall come. For as the lightning needeth none to herald or announce it, but is in an instant of time visible throughout the whole world, even to those that are sitting in their chambers, so the coming of Christ shall be seen every where at once, because of the brightness of His glory. Another sign He adds of His coming, Wheresoever the body is, thither will the eagles be gathered together. The eagles denote the company of the Angels, Martyrs, and Saints.
