The same divine authority that forbids the killing of a human being establishes certain exceptions, as when God authorizes killing by a general law or when He gives an explicit commission to an individual for a limited time.
Recognize in this bread what hung on the cross, and in this chalice what flowed from His side... whatever was in many and varied ways announced beforehand in the sacrifices of the Old Testament pertains to this one sacrifice which is revealed in the New Testament.
Sin is to a nature what blindness is to an eye. The blindness of an evil or defect which is a witness to the fact that the eye was created to see the light and, hence, the very lack of sight is the proof that the eye was meant... to be the one particularly capable of seeing the light. Were it not for this capacity, there would be no reason to think of blindness as a misforture.
Six is a number perfect in itself, and not because God created the world in six days; rather the contrary is true. God created the world in six days because this number is perfect, and it would remain perfect, even if the work of the six days did not exist.
The customs of God's people and the institutions of our ancestors are to be considered as laws. And those who throw contempt on the customs of the Church ought to be punished as those who disobey the law of God.
Samson crushed himself and his enemies to death beneath the ruins of a building. He can only be excused on the grounds that the Spirit of the Lord, who wrought miracles through him, had bidden him to do so. But, apart from such men excepted by the command of a just law in general or of God, the very Source of justice, in a special case, any one who kills a human being, himself or another, is guilty of murder.
Let us, on both sides, lay aside all arrogance. Let us not, on either side, claim that we have already discovered the truth. Let us seek it together as something which is known to neither of us. For then only may we seek it, lovingly and tranquilly, if there be no bold presumption that it is already discovered and possessed.
