Great is the Lord, and greatly to be praised: and of his greatness there is no end.

“Now if any one should ask for some interpretation, description and explanation of the divine essence, we are not going to deny that we are unlearned in this kind of wisdom, acknowledging only so much as this, that it is not possible that which is by nature infinite should be comprehended in any conception expressed by words. The fact that the divine greatness has no limit is proclaimed by prophecy, which declares expressly that of his splendor, his glory and his holiness, "there is no end." If his surroundings have no limit, much more is he himself in his essence, whatever it may be, comprehended by no limitation in any way. If then interpretation by way of words and names implies by its meaning some sort of comprehension of the subject, and if, on the other hand, that which is unlimited cannot be comprehended, no one could reasonably blame us for ignorance, if we are not bold in respect of what none should venture on. For by what name can I describe the incomprehensible? By what speech can I declare the unspeakable? Accordingly, since the Deity is too excellent and lofty to be expressed in words, we have learned to honor in silence what transcends speech and thought. If he who "thinks more highly than he ought to think" tramples on this cautious speech of ours making a jest of our ignorance of things incomprehensible, and recognizes a difference of unlikeness in that which is without figure, or limit, or size or quantity (I mean in the Father, the Son and the Holy Spirit) and brings forward to reproach our ignorance that phrase that is continually alleged by the disciples of deceit, " 'You worship you know not what,' if you know not the essence of that which you worship," we shall follow the advice of the prophet. We shall not fear the reproach of fools or be led by their reviling to talk boldly of things unspeakable. That unpracticed speaker Paul we make our teacher in the mysteries that transcend knowledge. He is so far from thinking that the divine nature is within the reach of human perception that he calls even the judgments of God "unsearchable" and his ways "past finding out." He affirms that the things promised to them that love him, for their good deeds done in this life, are above comprehension so that it is not possible to behold them with the eye, or to receive them by hearing or to contain them in the heart.”

“You cannot, then, heretic [Arian], build up a false doctrine on the basis of an analogy of human procreation. Nor can you gather the means for such a purpose from our discussion, for we cannot embrace the greatness of infinite godhead, "of whose greatness there is no end," in our limited speech. If you should seek to give an account of a human's birth, you must certainly point to a time. But the divine generation is above all things. It reaches far and wide, and it rises high above all thought and feeling. For it is written, "No one comes to the Father, except by me." Whatever, therefore, you conceive concerning the Father—yes, even his eternity—you cannot conceive anything concerning him except with the Son's aid nor can any understanding ascend to the Father except through the Son. "This is my dearly beloved Son," the Father said. "Is," please note, means that who he is, and what he is, is [true] forever. Hence David is also moved to say, "O Lord, your Word abides forever in heaven," for what abides fails neither in time nor in eternity.”

“"Great is the Lord, and very much to be praised" (ver. 3). How much was he about to say? what terms was he about to seek? How vast a conception hath he included in the one word, "very much"? Imagine what thou wilt, for how can that be imagined, which cannot be contained? "He is very much to be praised. And of His Greatness there is no end;" therefore said he "very much:" lest perchance thou begin to wish to praise, and think that thou canst reach the end of His praises, whose Greatness can have no end. Think not then that He, whose Greatness has no end, can ever be enough praised by thee. Is it not then better that as He has no end, so neither should thy praise have end? His Greatness is without end; let thy praise also be without end. ...”

“Great is the Lord: Even if one says, "I will magnify and praise Him," He is already great and praised beyond all praises to the extent that: And his greatness is unsearchable: A person cannot comprehend it through much investigation, for it is unsearchable. Nevertheless, a person should praise Him according to their understanding.”

“Great is the Lord, and greatly to be praised,.... Christ is the great God as well as our Saviour; great in all the perfections of his nature, of great wisdom, power, faithfulness, holiness, grace, and goodness; great in his person as God-man, God manifest in the flesh; great in all his offices and relations he bears and stands in to his people; and great in all his works of creation, providence, and redemption, in which he is concerned; and upon all which accounts he is to be praised, and greatly to be praised, by his people, even to the utmost of their capacities, here and hereafter; see Psa 48:1; and his greatness is unsearchable; the greatness of his nature, and the perfections of it, these are past finding out; and so are his ways and works, and the riches of his grace, Joh 11:7. The Targum is, "and of his greatness there is no end.'' So the Septuagint, Vulgate Latin, Syriac, and Arabic versions.”
