Ecumenism in common use can refer to two different ideas, either relations with non-Christian or non-Orthodox religious groups or instead it is the teaching that the Orthodox Church is not uniquely the one Church of Jesus Christ but rather one of many branches. The former activity can be of dubious value to some, while the latter is considered a heresy by many. To many in the Orthodox Church, participation in ecumenical relations with other religious groups is often an indication that the teaching regarding the Orthodox Church's non-uniqueness is being promulgated, either openly or surreptitiously.
