About Angels

Angels are spirit beings (Hebrews 1:14), so they do not have any essential physical form. It definitely seems that angels have the ability to take on human form. In Genesis 18:1-19, God and two angels appeared as men and actually ate a meal with Abraham. Angels appear as men many times throughout the Bible (Joshua 5:13-14; Mark 16:5). The angelic creatures described in Isaiah 6, Ezekiel 10, and Revelation 4-5 appear quite unusual. So, angels have some form of “spiritual body” but likely we are currently incapable of truly understanding their form. Angels also have the ability to take on other forms, such as human, in order to appear to us in a manner we can understand. Whenever angels did appear to humans in the Bible, it resulted in fear, amazement, and wonder (see Daniel chapter 10).
The Bible does not necessarily support the gender of angels being male or female. Whenever gender is “assigned” to an angel in Scripture, it is male (Genesis 19:10,12; Revelation 7:2; 8:3; 10:7). This does not indicate that angels are male though. Matthew 22:30 is probably indicating that angels are “sexless.” If angels do not procreate, why would they need a gender? In a similar manner, God always refers to Himself in masculine language, although God is neither male nor female. He just uses masculine language because it more adequately describes who He is and what He does. If angels do have a gender, Scripture would indicate that they are predominately or universally male. It is more likely that angels are genderless, just as God is, and that masculine language is just used to describe them and their role in serving God.
