The answer
"Ecumenical Council":
A gathering of the shepherds and teachers of the Church from all the regions of the world to examine a matter that concerns the Christian Faith, with the aim of preserving the order and soundness of the Faith among the Christians throughout the entire world.
This expression is similar to the expression “international conference.” However, the concern is not with nations, but rather with the Christian churches in different countries.
"Heretic":
An innovator, who proclaims a teaching that is contrary to what was recorded in Holy Scriptures. He also does not adhere to the teachings of the Church, which were proclaimed by Her Fathers throughout the centuries, and is thus referred to as a “heresiarch.” He is tried by an ecclesiastical (church) council that is either ecumenical or local. A range of disciplines are possible, the most serious of which is “excommunication” or “anathematisation,” which is his rejection from amongst the Christians, because he has disturbed the peace of the Church (2 John 1:10).
