Gregory the Dialogist

Concerning this glory of His Ascension, Habakkuk also says, "The sun was lifted up, and the moon stood in its order." For who is designated by the name of sun except the Lord, and who by the name of moon except the Church? For until the Lord ascended to heaven, His holy Church utterly feared the adversities of the world; but after it was strengthened by His Ascension, it openly preached what it secretly believed. Therefore the sun was lifted up, and the moon stood in its order, because when the Lord sought heaven, His holy Church grew in the authority of preaching.
