And if any one would distinguish such notions by words, he would find it absolutely necessary to call that which admits of no changing to the worse unchanging and invariable, and to call the First Cause of all ungenerate, and that which admits not of corruption incorruptible; and that which ceases at no limit immortal and never failing; and that which presides over all Almighty. And so, framing names for all other Divine attributes in accordance with reverent conceptions of Him, we designate them now by one name, now by another, according to our varying lines of thought, as power, or strength, or goodness, or ungeneracy, or perpetuity.
