Religious excommunication is still practiced today by mormon, catholic, lutheran and Jehovah witness churches and it has both pros and cons: The positive side is when it is a personal choice for someone like a priest choosing to defrock and excommunicate themselves or an atheist deciding to leave religion. It can however be dehumanising when it is forced onto people like pregnant teenagers, gay people, secular musicians and prostitutes.
What are the main reasons for excommunication?
* Procuring of abortion
* Apostasy: The total rejection of the Christian faith.
* Heresy: The obstinate post-baptismal denial of some truth, which must be believed with divine and Catholic faith.
* Schism: The rejection of the authority and jurisdiction of the pope as head of the Church.
Excommunication can be a public process, just like the Pope did with the Mafia, or it could be non-public. And, if your excommunication ends, it may be a public or a private process. If someone modifications or reforms his or her life, he or she may be taken returned into the church, absolutely.
Apostasy is the rejection of Christ by one who has been a Christian….” “Apostasy is a theological class describing those who’ve voluntarily and consciously abandoned their faith in the God of the covenant, who manifests himself most absolutely in Jesus Christ.”
Excommunication severs one from communion with the Church; excommunicated Catholics are forbidden from receiving any sacrament and refused a Catholic burial, but are nevertheless bound by means of canonical obligations together with attending Mass or fasting seasonally.
Although the act of “formal defection” from the Catholic Church has therefore been abolished, public or “notorious” (within the canonical sense) defection from the Catholic religion or from the communion of the Church is of path possible, as is expressly identified inside the Code of Canon Law.
