Whether it is necessary for the accusation to be made in writing?

Objections

Objection 1 : It would seem unnecessary for the accusation to be made in writing. For writing was devised as an aid to the human memory of the past. But an accusation is made in the present. Therefore the accusation needs not to be made in writing.
Objection 2 : Further, it is laid down (Decret. II, qu. viii, can. Per scripta) that "no man may accuse or be accused in his absence." Now writing seems to be useful in the fact that it is a means of notifying something to one who is absent, as Augustine declares (De Trin. x, 1). Therefore the accusation need not be in writing: and all the more that the canon declares that "no accusation in writing should be accepted."
Objection 3 : Further, a man's crime is made known by denunciation, even as by accusation. Now writing is unnecessary in denunciation. Therefore it is seemingly unnecessary in accusation.
