The third commandment: “Remember the sabbath day to sanctify it.” This third commandment imposes a regular periodical holiday—quietness of heart, tranquility of mind, the product of a good conscience. Here is sanctification, because here is the Spirit of God. Well, here is what a true holiday, that is to say, quietness and rest, means “Upon whom,” he says, “shall my spirit rest? Upon one who is humble and quiet and trembles at my words.” So unquiet people are those who recoil from the Holy Spirit, loving quarrels, spreading slanders, keener on argument than on truth, and so in their restlessness they do not allow the quietness of the spiritual sabbath to enter into themselves.
