Ambrose of Milan

Therefore, pay attention to yourself, poor man, pay attention, wealthy man; because there are trials in both poverty and riches. And therefore the Wise Man says: Do not give me riches or poverty, give me only what is sufficient for me. Because riches, like feasts, stretch the stomach and the mind with worries and anxieties. And therefore he asks to be established with what is necessary and sufficient: Lest, he says, being filled, I become a liar and say: Who sees me? But if I become poor, I will commit theft and swear in the name of the Lord (Ibid.). Therefore, the temptations of the world must be avoided and guarded against; lest the poor despair and the wealthy become arrogant.

An eagle and a ship and a serpent are not of one family and nature but of a distinguishable and different substance, and yet they are three. On the testimony of Scripture, therefore, [the Arians] learn that their arguments are against themselves.Therefore, in saying that the substance of the Father and of the Son is diverse and their Godhead distinguishable, [the Arians] themselves assert there are two gods. But we, when we confess the Father and the Son, in declaring them still to be of one Godhead, say that there are not two gods but one God. And this we establish by the Word of the Lord.

The beauty of a good thing pleases the more, if it be shown under various aspects. For those are good things, whereof the texture of the priestly robe was the token, that is to say, either the Law or the church, which latter has made two garments for her spouse, as it is written—the one of action, the other of spirit, weaving together the threads of faith and works.
