The ODCC on the tolerati, vivandi

tolerati (Lat., ‘tolerated persons’). The technical term formerly used in canon law for those excommunicated persons with whom the faithful were permitted to have some measure of intercourse. They were thus distinguished from the vitandi (q.v.). These categories are no longer used in RC canon law.

vitandi (Lat., ‘persons to be avoided’). The technical name formerly used in canon law for those excommunicated persons with whom members of the Church were debarred from having any kind of intercourse unless there was reasonable cause. They were distinguished from the tolerati, with whom relations of a personal kind were more readily allowed. Unless he had laid violent hands upon the Pope, in which case ipso facto he was vitandus, an offender acquired this status only when he was expressly so named by the Roman see. These rulings are embodied in the Codex Iuris Canonici (1917), cans. 2258, 2259, and 2343. The category is not used in the 1983 Codex.
