Forgiveness without Forgetfulness

From Volume 3, Chapter 15 of Jane Austen's Pride and Prejudice:

Mr. Collins writes of Mr. and Mrs. Wickham: "You ought certainly to forgive them as a christian, but never to admit them in your sight, or allow their names to be mentioned in your hearing."

Mr. Collins, the esteemed rector of Hunsford, gives such an amazing illustration of his notion of Christian forgiveness.  Thou shalt forgive, but apparently, never forget.  This brought to my mind a great post on the Texas Faith blog: What is the sin in your faith?  Read all the responses: very powerful, challenging stuff.
