What is the difference between priest vs pastor?
The main difference between a priest and a pastor is one of ordination. Priests are ordained by bishops, while pastors are not. A priest may be the leader at a parish church or cathedral or other Catholic institution, though it could also be the bishop of that particular diocese.
Priesthood is usually bestowed by the Roman Catholic Church after earning a baccalaureate degree in philosophy and theology followed by 7-9 years of study. Pastors receive their ordination on an ad hoc basis at the local church level with consideration given to many factors such as age, completed seminary schooling, pastoral experience, teaching capability and administrative abilities.
They both preach but priests know more scripture because they have studied it for 7 years.
