Revalations 6:6-8
5 Out from the throne come flashes of lightning and sounds and peals of thunder And there were seven lamps of fire burning before the throne, which are the seven Spirits of God;
6 and before the throne there was something like a (Q)sea of glass, like crystal; and in the center and around the throne, four living creatures full of eyes in front and behind.
7 The first creature was like a lion, and the second creature like a calf, and the third creature had a face like that of a man, and the fourth creature was like a flying eagle.
8 And the four living creatures, each one of them having six wings, are full of eyes around and within; and day and night they do not cease to say, "HOLY, HOLY, HOLY is THE LORD GOD, THE ALMIGHTY, WHO WAS AND WHO IS AND WHO IS TO COME."
In a word, those weren’t angels, but ministering beings. Read my original post.
Don't you think maybe the feathers would have been a dead give-away???
Also in Isaiah’s theophany in the temple the seraphim have 6 wings.
However, the abp may be following Gregory the Great’s thought, which is that “Angel” denotes a job (and the ‘person’ doing it). The job is being a messenger. (Both Malak and angelos mean messenger in Hebrew and Greek respectively.) So if we don’t have accounts of winged beings delivering messages, then the abp could be understood as right.
