They are called Catholic because unlike Paul's letters that were each addressed to a specific church to deal with specific problems, the Catholic Letters are addressed to the whole Church. They are truly universal.
Two the Church returns to Ordinary Time and we pick up at the Seventh Week, and the first reading picks up in the middle of chapter 3 of the Letter of James, it would be valuable to take a few moments today and read chapters 1 and 2. James is direct, dealing head on with temptation, doubt, faith, and what he calls the double-minded, or double-spirited person. This is the person who wants to be Christian but not really let go of their attachment to the world. From time to time it is any of us.
