A parish is the smallest unit of administration within the Anglican church.
Most parishes have just one church, called the parish church.
Parishes combine into dioceses . Mass. A person becomes a priest by being ordained by a bishop . Most bishops require special training for this, which is typically obtained in a theological college or seminary. In general no one cares about these provinces except church employees. In some parts of the world, typically those that were never English colonies, the number of Anglicans is small enough that there are not individual national churches.
