[Marcus Marulus]

Union of Christian Churches on the basis of the lowest possible denominator (some basic dogmas), after that a "reconciliation" with Judaism and Islam - this is a very old Rosicrucian idea first espoused by a Czech writer and theologian Jan Amos Komensky-Comenius (17th century) in his treatise Lux ex Oriente. His idea of the Union of Churches was not that supported by most of his contemporaries, who wanted all Christianity to become either Roman Catholic (ie. recognition of Pope as supreme leader of the Church), or Eastern Orthodox (the Orthodox saw possibility of the reunion of Christianity in terms of acknowledging the equality of all patriarchs, without one supreme head, that is the Orthodox conception of the Church) or Protestant (Church without priesthood and mass).

Comenius wanted some supreme body to be formed, which would consist of "elders" chosen from all these Churches. This sort of a council would be supreme authority in the whole Christianity. The authority of the traditional hierarchy (Pope, bishops, priesthood, patriarchs...) would thus become secondary in importance. This supreme body, chosen from representatives from all Churches, would then lead Christianity in an "Ecumenical" direction and prevent religious conflicts. The true precursor of the modern Ecumenism!

Comernius was also inventor of the modern concept of school education. Just a coincidence?
