Zealotry

Ecclesiastical rigorism — the tendency to demand absolute strictness in canonical matters, refusing all economy.

Zealotry (zelotismos) in Orthodox canonical usage refers to the rigorist position that insists on akribeia (strictness) in all canonical matters, refusing any application of economia (pastoral flexibility). The most significant historical expression is the Old Calendarist movement, which broke with the Greek Church over the calendar reform of 1924. Zealotry is distinct from healthy insistence on canonical integrity: the zealot refuses to recognize that the Church herself has authority to apply economia, reducing canonical norms to absolute laws that admit of no pastoral application.
