Justinian the Great

“The three most ancient opinions concerning God are Anarchia, Polyarchia, and Monarchia. The first two are the sport of the children of Hellas, and may they continue to be so. For Anarchy is a thing without order; and the Rule of Many is factious, and thus anarchical, and thus disorderly. For both these tend to the same thing, namely disorder; and this to dissolution, for disorder is the first step to dissolution. But Monarchy is what we hold in honor.”
― Gregory Nazianzus

“Wisdom is not to be found in the art of oratory, or in great books, but in a withdrawal from these sensible things and in a turning to the most simple and infinite forms. You will learn how to receive it into a temple purged from all vice, and by fervent love to cling to it until you may taste it and see how sweet That is which is all sweetness. Once this has been tasted, all things which you now consider as important will appear as vile, and you will be so humbled that no arrogance or other vice will remain in you. Once having tasted this wisdom, you will inseparably adhere to it with a chaste and pure heart. You will choose rather to forsake this world and all else that is not of this wisdom, and living with unspeakable happiness you will die.”
― Nicolaus Cusanus

“Grant me, O Lord my God, a mind to know you, a heart to seek you, wisdom to find you, conduct pleasing to you, faithful perseverance in waiting for you, and a hope of finally embracing you. Amen.”
― Thomas Aquinas

“And, I rejoice to say, to one great mischief I have from the first opposed myself. For thirty, forty, fifty years I have resisted to the best of my powers the spirit of liberalism in religion. Never did Holy Church need champions against it more sorely than now, when, alas! it is an error overspreading, as a snare, the whole earth; and on this great occasion, when it is natural for one who is in my place to look out upon the world, and upon Holy Church as in it, and upon her future, it will not, I hope, be considered out of place, if I renew the protest against it which I have made so often.”
