10 “All my bones shall say, Lord, who is like You”. Who can speak anything worthily of these words? I think them only to be pronounced, not to be expounded. Why do you seek this or that? What is like your Lord? Him have you before you. “The unrighteous have declared unto me delights, but not after Your law, O Lord!” Persecutors have been who have said, Worship Saturn, worship Mercury. I worship not idols (says he): “Lord, who is like You? They have eyes, and see not; ears have they, but they hear not.” “Lord, who is like You,” who hast made the eye to see, the ear to hear?
But I (says he) worship not idols, for them a workman made. Worship a tree or mountain; did a workman make them also? Here too, Lord, who is like You? Earthly things are shown unto me; You are Creator of the earth. And from these haply they turn to the higher creation, and say to me, Worship the Moon, worship this Sun, who with his light, as a great lamp in the Heavens, makes the day. Here also I plainly say, “Lord, who is like You?” The Moon and the Stars You have made, the Sun to rule the day have You kindled, the Heavens have You framed together.
There are many invisible things better. But haply here also it is said to me, Worship Angels, adore Angels. And here also will I say, “Lord, who is like You?” Even the Angels You have created. The Angels are nothing, but by seeing You. It is better with them to possess You, than by worshipping them to fall from You.
