From the article:
 
In Matthew, the pharisees ask Christ, "Is it lawful for a man to divorce his wife for any cause?"

Dear Mark,
 
Did you notice what the Pharasees asked?  Is it lawful...
 
Are we still under the Law since the cross?  Or did Jesus fulfill the Law for the Christian and now place His own under His covering grace?  Is the Christian free to re-marry after a divorce?  Grace says yes.  The words of Jesus quoted in the article were before the cross, before the Law was fulfilled
