Reason dictates that those who are truly pious and philosophers should honor and love only the truth, declining to follow the opinions of the ancients, if they are worthless. For not only does sound reason dictate that one should not follow those who do or teach unjust things, but the lover of truth should choose by all means, and even before his own life, even though death should remove him, to speak and do righteous things. – Justin Martyr, First Apology, #2.
Thirteenth Rule. To be right in everything, we ought always to hold that the white which I see, is black, if the Hierarchical Church so decides it, believing that between Christ our Lord, the Bridegroom, and the Church, His Bride, there is the same Spirit which governs and directs us for the salvation of our souls. Because by the same Spirit and our Lord Who gave the ten Commandments, our holy Mother the Church is directed and governed. – Ignatius of Loyola, founder of the Jesuits, “Spiritual Exercises”.
