An angel is a spiritual creature created by God for the service of Christendom and the church. They are sent to bring us messages from God’s heart.When angels visit us, we do not hear the rustle of wings, nor feel the feathery touch of the breast of a dove; but we know their presence by the love they create in our hearts.
Angels are bright still, though the brightest fell and they can fly because they carry no burdens.For when God said: “Let there be light, and there was light.” If we are justified in understanding in this light the creation of the angels, then certainly they were created partakers of the eternal light which are the unchangeable Wisdom of God.
By which all things were made and whom we call the only-begotten Son of God… God always has an angel of help for those who are willing to do their duty. The angels are as perfect in form as they are in spirit. They can fly because they take themselves lightly.
Gen 3:24 So he drove out the man and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life.
