(Rev. 14:6-7) “And I
saw another angel flying through the midst of heaven,” that is, the preaching
that was spreading in the midst of the Church. “Having the eternal Gospel,
to evangelize it to those who inhabit the earth and say to them: Fear the Lord,
etc.” There are some who want this angel who flies in the midst of heaven to be
Elijah, and the other angel who follows him, the companion of Elijah, who at
that time will preach the Gospel himself. (Caesarius of Arles Commentary on
Revelation: A Sixth Century Commentary on the Book of Revelation [trans.
