Consequently, in the tribunal of conscience he who is reasonably persuaded of his innocence cannot be compelled to treat himself as excommunicated and to seek absolution; this conviction, however, must be prudently established.
It does mean, though, that one is deprived of the benefits of full communion with the Catholic Church.Bishop Thomas Paprocki holds a similar view as that of Krupp and Peters.
[15] The Catholic Church claims that the penalty of excommunication is biblical and that both Paul of Tarsus and John the Apostle make reference to the practice of cutting people off from the community, in order to hasten their repentance.
The Catholic Encyclopedia states that from the earliest days of Christianity, excommunication was the chief (if not the only) ecclesiastical penalty for laymen; for guilty clerics the first punishment was deposition from their office, i.e. reduction to the ranks of the laity.

The tenth canon of the Council of York (1195) ordered all priests to publish censures of excommunication against perjurers with bell and lighted candle thrice in the year.
[21] From the middle of the fifteenth century, dueling over questions of honor increased so greatly, that in 1551 the Council of Trent was obliged to enact the severest penalties against it.
Dueling was forbidden; and the prohibition extended to not only the principals, but their seconds, physicians expressly brought to attend upon the scene, and all spectators not accidentally present.
Benedict XIV decreed that duelists should be denied burial by the Church even if they did not die on the dueling ground and had received absolution before death.

[2] Since 1418, the Catholic Church formally differentiated between excommunicated persons tolerati ("tolerated") and those vitandi ("to be avoided"), when Pope Martin V clearly drew this distinction in his apostolic constitution Ad evitanda scandala.
The second is inflicted by an ecclesiastical prelate, either when he issues a serious order under pain of excommunication or imposes this penalty by judicial sentence and after a trial.
Therefore, whether excommunications be a jure (by the law) or ab homine (under form of sentence or precept), they may come from the pope, from the bishop for his diocese; and from regular prelates for religious orders.
Baptism confers initial jurisdiction, delinquency refers to having committed a wrong, and contumacious indicates the person's willfull persistence in such conduct.
