Having read the letter of the five cardinals, it is sad to see, that after having played great lip service to their claimed concern for unity, charity and justice, they write a letter that pretends to be in question form, but in its content it is the summation of the work of judge, jury and executioner. 

Sad, very sad indeed. 

This is what the Pope refers to in his reference to the discernment of spirits in which an admonition has been delivered, and he is spot on!
