What is the difference between a diocesan priest and a religious priest?
A diocesan priest ordinarily serves the Church within a rather well defined area (a diocese). He ordinarily serves the people as a parish priest, but he may also be involved in many other forms of ministry: teaching, Chaplain in hospitals, prisons, campus ministry, etc. A religious priest, on the other hand, is a member of a community which goes beyond the geographical limits of any diocese.
