Angels have wings: it's how the Bible describes them

This is one of the most flatly corrected claims in Heiser's material. Scripture never describes an angel, as distinct from cherubim or seraphim, with wings. When angels show up interacting with people in the Old Testament, they look like ordinary men: the visitors to Lot in Genesis 19 are the clear example, since nobody in that story reacts to anything unusual about their appearance, and wings would have been hard to miss.

What people are actually picking up on is language like angels "descending" or "ascending," which sounds like flight but is describing origin and destination, not wings. "Descending" means coming from heaven; it doesn't mean flapping down, any more than the same language used of Jesus's return, or of believers' future ascent, means humans are expected to sprout wings. Cherubim and seraphim are a separate category and genuinely are described with wings (the seraphim's six wings in Isaiah 6, for instance), and Revelation's four living creatures borrow that seraphic wing-count while blending in features from Ezekiel's four-faced cherubim. But "angel" specifically, everywhere it names a messenger-type spiritual being, carries no wing description at all.

The point gets made pretty bluntly: even citing Philo, who does describe winged messenger-figures on the model of the Greek god Mercury, isn't enough to override what the biblical text itself says, because the rule is not to add details that aren't actually there. It's also worth separating this from an unrelated mix-up: the winged woman of Revelation 12 is a different image entirely, about a woman being carried to safety, and has nothing to do with whether angels have wings.
