In the old days (that is, before codified law), they had a term for an excommunicate who passed one (nb:
one) year without seeking reconciliation: Insordescence, a status that made one (especially clerics) liable to heightened penalties. See
Taunton, Law of the Church (1906) at 371. For clergy, these penalties were more or less along the lines of what we would today call “dismissal from the clerical state”.
