We must now inquire about the seal of confession.

Under this head there are five points of inquiry:

(1) Whether in every case a man is bound to hide what he knows under the seal of confession?

• (2) Whether the seal of confession extends to other matters than those which have reference to confession?
• (3) Whether the priest alone is bound by the seal of confession?
• (4) Whether, by permission of the penitent, the priest can make known to another a sin of his which he knew under the seal of confession?
• (5) Whether he is bound to hide even what he knows through other sources besides?
