Are angels male or female?

Angels are referred to in the Hebrew language as bene elohim, or "sons of God." Bible scholar Dr. Henry Morris says about the angels:

"The only obvious and natural meaning [of the designation, “sons of God”]... is that these beings were sons of God, rather than of men, because they had been created, not born. Such a description, of course, would apply only to Adam (Lk. 3:38) and to the angels, whom God had directly created (Psa. 148:2, 5; 104:4; Col. 1:16)." Dr. Morris explains further:

"Whenever angels have appeared visibly to men, as recorded in the Bible, they have appeared in the physical bodies of men. Those who met with Abraham, for example, actually ate with him (Gen. 18:8) and, later, appeared to the inhabitants of Sodom in such perfectly manlike shape that the Sodomites were attempting to take these ‘men’ for homosexual purposes. The writer of Hebrews suggests that, on various occasions, some ‘have entertained angels unawares’ (Heb. 13:2).

‘It is true that the Lord Jesus said the resurrection they ‘neither marry, nor are given in marriage, but are as the angels of God in heaven’ (Mat. 22:30). However, this is not equivalent to saying that angels are "sexless," since people who share in the resurrection will surely retain their own personal identity, whether male or female.

Furthermore, angels are always described, when they appear, as ‘men,’ and the pronoun ‘he’ is always used in reference to them. Somehow they have been given by God the capacity of materializing themselves in masculine human form when occasion warrants, even though their bodies are not under the control of the gravitational and electromagnetic forces which limit our own bodies in this present life."
