Ruckman teaches that angels have no wings (Theological Studies, Booklet 18, p. 5). Ruckman has to deny that Seraphims are angels, as they have wings (Isa. 6:2). Cherubims are also described with wings in Eze. 10:5, and in other passages. Note also that Dan. 9:21 and Rev. 14:6 describes an angel flying. However, notice how he put wings on the angels in his artwork he drew for the book Ruckman's Apocalypse (he did it multiple times). In the introduction Ruckman excused himself saying that "if you don't put wings on them, the average person will not know what they are; not even the average Christian." Without having a Scripture reference to prove it, Ruckman also teaches that angels are all 33 year old males. You may also be interested in knowing that Ruckman teaches that angels are stars (The Book of Matthew. 1978, p. 32). We believe it is more accurate to teach that angels are sometimes symbolized by stars in Revelation, but to say that they are stars without pointing out any symbolism is really stretching it.
