Whether before the public denunciation witnesses ought to be brought forward?

Objections

Objection 1 : It would seem that before the public denunciation witnesses ought not to be brought forward. For secret sins ought not to be made known to others, because by so doing "a man would betray his brother's sins instead of correcting them," as Augustine says (De Verb. Dom. xvi, 7). Now by bringing forward witnesses one makes known a brother's sin to others. Therefore in the case of secret sins one ought not to bring witnesses forward before the public denunciation.
Objection 2 : Further, man should love his neighbor as himself. Now no man brings in witnesses to prove his own secret sin. Neither therefore ought one to bring forward witnesses to prove the secret sin of our brother.
Objection 3 : Further, witnesses are brought forward to prove something. But witnesses afford no proof in secret matters. Therefore it is useless to bring witnesses forward in such cases.
Objection 4 : Further, Augustine says in his Rule that "before bringing it to the notice of witnesses . . . it should be put before the superior." Now to bring a matter before a superior or a prelate is to tell the Church. Therefore witnesses should not be brought forward before the public denunciation.
