Are all angels male or are some female?

TL;DR:

Angels are spirit beings, but all the descriptions of angels in the Bible are of males. Whether male or female, what is important is understanding that God made the angels, that angels serve His purposes, and that we are to worship the God who made the angels.

what does the bible say?

The Bible consistently refers to angels using masculine pronouns and presents them in male form, with no examples of female angels. The Greek word for "angel" in the New Testament, angelos, is a masculine noun without a feminine form. While angels in Scripture are depicted as male, their spiritual nature transcends human gender classifications. Instead of focusing on their gender, we must focus on their messages and missions. In the end, we would do well to be content with what Scripture has communicated on the subject. Angels are God's ministering spirits, sent to serve the Lord's purposes. Whether angels are male or female is ultimately less important than whether we know and love the Lord of the angels.

from the old testament

Every reference to angels in the Bible uses the masculine gender. An angel is always a "he" rather than a "she" or an "it."
When angels appear in human form in Scripture, they are always male (Genesis 18:2, 16; Ezekiel 9:2). There are no examples of angels presenting themselves as females in Scripture.
The angel Gabriel is described in Daniel 8:16 and Daniel 9:21 as "the man Gabriel."
Michael is described in Daniel 10:13 and Daniel 10:21 as "one of the chief princes."

from the new testament

The Greek word for "angel" in the New Testament is angelos, itself a masculine noun. A feminine form of this word does not exist.
The angels mentioned throughout the visions of Revelation are referred to with the pronouns "he" and "his."
Matthew 22:30 reads: "For in the resurrection they neither marry nor are given in marriage, but are like angels in heaven." Nothing here negates or confirms the idea of angels being masculine; all this verse teaches is that marriage does not take place among angels.
In Luke 1:19 and Luke 1:26, the angel Gabriel is referred to with masculine pronouns as he brings messages to Zechariah and Mary.
In Jude 1:9 and Revelation 12:7, the angel Michael is referred to with masculine pronouns as he contends with the devil and leads angels in heavenly warfare.

implications for today

Recognizing that the spiritual nature of angels transcends human gender classifications, even if they appear as males in the Bible, reminds us to look beyond earthly perspectives when considering divine beings. This shift in focus encourages us to pay attention to their messages and missions rather than their physical forms, emphasizing the divine purposes they serve. By doing so, we are prompted to seek and heed God's guidance and support in our own lives, understanding that His ways and messengers operate beyond our limited human understanding. This perspective helps us appreciate the deeper spiritual realities that God reveals through His angels. It urges us to trust in His divine plan and to remain open to the ways He communicates with us.
