Today's entrance antiphon, Acts 1.11: Men of Galilee, why gaze in wonder at the heavens? This Jesus whom you saw ascending into heaven will return as you saw him go. This was said by two men dressed in white garments who suddenly appeared beside the disciples who were looking intently at the sky after seeing Jesus being lifted up and taken from their sight by a cloud. This account of the Ascension as witnessed by many is undeniable. It's also inevitable that he who has ascended will return again.
