Marcos 12
Athanasius of Alexandria · Comentário Patrístico (catena)
Marcos 12:29
Since God is one, it is ridiculous to suppose that there could be still another "Lord" of heaven and earth in addition to the Lord who is one. There is simply no room for a second Lord of all, if the one true God fills all things in the compass of heaven and earth. — Against the Heathen 6.4
