The legal terms used within the Church are:
- Secular priest: for a priest who is not a consecrated religious. This includes diocesan priests, priests who belong to priestly fraternities such as the SSPX, FSSP and priests who belong to priestly societies such as Maryknoll, Vincentians et al.
- Regular priest: for a priest who is also a consecrated religious bound by vows to follow a rule of life. These men are priests who are also members of any of these: orders, congregations, and societies of apostolic life. These are friars, monks, hermits or clerks regular.
Each of these priests has a different superior. The most commonly known priests are those who are diocesan. These are secular priests who are incardinated into a specific diocese and the local bishop is their major superior. This is usually your parish priest.
Priests who belong to other groups do not answer to the bishop, but to the superior of their specific institute.
If a priest is a either a monk or a friar he is canonically a religious brother, but he is an ordained brother. There are many friars and monks who are not ordained brothers. They are called lay brothers. But both, the ordained and the lay in a friary or monastery have equal rights and the same vocation, that is the call to achieve the perfection of charity in the manner prescribed by the rule of the order.
If a priest is a religious, but is not a monk, friar or hermit, he is called a clerk regular. For example, Jesuits, Salesians, Redepmptorists, Passionists, Fathers of Mercy, Oblates of Mary Immaculate, etc, these are all clerks regular. They are religious, but are not monks, friars or hermits.
It can be confusing until you get used to the differences.
