The other kind of minister in the Roman Catholic Church is a person who ministers a sacrament, meaning that he or she is a conduit of the sacramental power. This is not an office or position but instead a function that different kinds of people may perform, depending on the sacrament. There are two kinds of ministers in this sense. The ordinary minister of a sacrament has both the spiritual power to perform the sacrament (i.e. a valid sacrament) and the legal authority to perform the sacrament (i.e. a licit sacrament). An extraordinary eucharistic minister (Latin: minister extraordinarius) has the spiritual power but may only perform the sacrament in certain special instances under canon law (i.e. emergencies). If an extraordinary minister performs a sacrament illegally, the sacrament still happens but the person ministering could be liable for an ecclestiastical penalty, such as the interdict. If a person who is neither an ordinary nor an extraordinary minister attempts to perform a sacrament, no supernatural effect happens, i.e., the putative sacrament is not merely illicit, but invalid).

Notes

1. Clergy means a bishop, priest, or deacon.
2. The Eucharist has two parts. The first part of the Eucharistic sacrament is the consecration, or the prayer over the gifts that the priest or bishop says. This is when transubstantiation occurs, according to Catholics.
3. The second part of the Eucharist is communion, or the distribution of the consecrated elements. More people may participate as ministers in this part, so it is treated separately.
4. Since Holy Orders has special rules when ordaining a bishop, the bishop ordination is treated separately.
