'Angels' in the Bible

And, beyond controversy, great is the mystery of our religion-- that Christ appeared in human form, and His claims justified by the Spirit, was seen by angels and proclaimed among Gentile nations, was believed on in the world, and received up again into glory.

I solemnly call upon you, in the presence of God and of Christ Jesus and of the elect angels, to carry out these instructions of mine without prejudice, and to do nothing from partiality.
