The Orthodox Church of Christ is the Body of Christ, a spiritual organism whose Head is Christ. It has a single spirit, a single common faith, a single and common catholic consciousness, guided by the Holy Spirit; and its reasonings are based on the concrete, definite foundations of Sacred Scripture and Sacred Apostolic Tradition. This catholic consciousness is always with the Church, but, in a more definite fashion, this consciousness is expressed in the Ecumenical Councils of the Church. From profound Christian antiquity, local councils of separate Orthodox Churches gathered twice a year, in accordance with the 37th Canon of the Holy Apostles.18 Likewise, often in the history of the Church there were councils of regional bishops representing a wider area than individual Churches and, finally, councils of bishops of the whole Orthodox Church of both East and West. Such Ecumenical Councils the Church recognizes as seven in number. The Ecumenical Councils formulated precisely and confirmed a number of the fundamental truths of the Orthodox Christian Faith, defending the ancient teaching of the Church against the distortions of heretics. The Ecumenical Councils likewise formulated numerous laws and rules governing public and private Christian church life, which are called the Church canons, and required the universal and uniform observance of them. Finally, the Ecumenical Councils confirmed the dogmatic decrees of a number of local councils, and also the dogmatic statements composed by certain Fathers of the Church — for example, the confession of faith of St. Gregory the Wonderworker, Bishop of Neo-Caesarea,19 the canons of St. Basil the Great,20 and so forth.
