THE DOCTRINE OF CHARITY

Inasmuch as good makes heaven with man, and evil makes hell, it is of the utmost importance to know what good is, and what evil is. It has already been said that good is that which belongs to love to the Lord, and to charity toward the neighbor; and that evil is that which belongs to the love of self and the love of the world. Hence it follows that it is from the loves, and from these alone, that it can be known what good is, and what evil is.
