He who trusts everyone and he who trusts none, are both destroyed. Although both attitudes are deadly, if you had to choose between them, it would be better to suffer wrong from the courage of your trust, instead of always being suspicious of all men.

Precepts..., Patrologia Graeca156.329

All who have the same reference and relationship with the first and all-perfect good, they all love each other and are made good, because they have with each other the exact same relationship.

On virtue..., speech II, Patrologia Graeca156.412

Ἀπόλωλεν ἅπας, ὁ πᾶσί τε πιστεύων καὶ μηδενί. Ὄντοιν δὲ δυοῖν θανασίμοιν, εἰ ἀναγκαίαν θείη τις τουτωνὶ τὴν αἵρεσιν, κρεῖσσον παθεῖν ἀπὸ τοῦ θαρρεῖν ἢ τοῦ πάντας ὑποπτεύειν ἑξῆς ἀνθρώπους.

Διὰ τὴν κοινὴν ἀναφοράν τε καὶ σχέσιν, ὡς ἄν τις εἴποι, τὴν πρὸς τὸ πρῶτον καὶ ὑπερτέλειον ἀγαθόν, πάντα ἀγαθύνεται καὶ φιλεῖται, ἔχοντα πρὸς ἄλληλα σχετικῶς.
