Whether the priest alone is bound by the seal of confession?

❌ Objection 1 : It would seem that not only the priest is bound by the seal of confession. For sometimes a priest hears a confession through an interpreter, if there be an urgent reason for so doing. But it seems that the interpreter is bound to keep the confession secret. Therefore one who is not a priest knows something under the seal of confession.

❌ Objection 2 : Further, it is possible sometimes in cases of urgency for a layman to hear a confession. But he is bound to secrecy with regard to those sins, since they are told to him as to God. Therefore not only the priest is bound by the seal of confession.

❌ Objection 3 : Further, it may happen that a man pretends to be a priest, so that by this deceit he may know what is on another's conscience: and it would seem that he also sins if he divulges the confession. Therefore not only the priest is bound by the seal of confession.
