Appendix: The Idea of Doctrinal Development in Eastern Orthodox Theology
By Fr Aidan Nichols
In Eastern Orthodox theology, the idea of dogma possesses specific characteristics of its own - owing to its special relationship with the doctrine of the Spirit, with the Orthodox teaching on Tradition, with the theology of the Councils, and with the notion of the infallibility of the Church as a whole. In this, Orthodox theology has, most notably, preserved one vital feature of the primitive Christian concept of dogma, namely, its inseparable relationship with the liturgical life of the Church.
Negatively, this leads Orthodox spokesmen to draw attention to the apophatic character of dogma.
Dogma's negative form (in ruling out certain avenues of thought as cul-de-sac) expresses a self-conscious inadequacy
of the human mind before the Christian mystery. Dogma does not exhaust the fullness of revelation, nor that of
Christian experience. Put positively: dogma is, in the words of Paul Evdokimov, the 'verbal
icon of truth', a symbol of the indescribable mystery,  Dogma upholds the mystery; it leads into it; and it expresses it, but apophatically - as in the celebrated
case of the dogmatic horos of Chalcedon, with its four
negative qualifications of the Union. The making of dogma contributes to the keeping of the Church's unity, yet
new definition has never been considered as an aim in itself. Rather is it an extraordinary measure directed against
disruption of that unity by false teaching.
For his French counterpart Olivier Clement, a convert to Orthodoxy, dogma is the 'adoration of the human mind', an act of precise thinking, yet not about the mystery, but rather in it. 
The formulation of dogmatic statements is seen by Orthodox writers as a theandric process, in which both God and man are involved. The Holy Spirit co-operates with human actors, as in the words of the 'apostolic council' in Acts 15, 'It has seemed good to the Holy Spirit and to us'. From an historical standpoint, the dogmas of the ecumenical councils were shaped in a human attempt to overcome aporiai and dialectical contradictions.  But at the same time, the patristic Church affirmed that she was guided by the Holy Spirit, and, thanks to this guidance, would preserve her identity, and the continuity of her nature and belief, intact. The consensus of bishops, united during a council as bearers of the supreme authority of the Church, is a sign of the presence and operation of the Holy Spirit, while the consensus of the entire People of God, expressed in the reception of the dogmatic defmitions by believing Christians as a whole certifies the theandric character of these dogmata.
Orthodox writers sometimes distinguish between the 'biblical character' of dogma, which it owes to its condition as a truth revealed by God, and its 'ecclesiastical character', which follows on from its definition by an ecumenical council and acceptance by the Church as a whole. So far as the vital biblical source is concerned, the need for such a scriptural reference explains the Orthodox hostility not only to the content of the Catholic dogma of Mary's Immaculate Conception (deemed extraneous to, or even contradictory of, the Scriptures) but also to the dogmatic form of belief in the glorious Assumption of the Blessed Virgin in the Catholic Church. Since - according to these theologians - the Bible does not mention Mary's Assumption, and only the liturgical tradition, together with mediaeval Byzantine theology, treats of it, there is no call to dogmatise that event, or to regard it as occupying an integral place in the economy of human salvation. No dogmatic statement can add to the contents of Scripture.  Relevant to this is the conviction of an apparent majority of Orthodox theologians that Tradition is not a second source of revelation, parallel to the Bible. Rather is it that reality thanks to which, and owing to the presence of the life-giving Spirit, the Church transmits the sense, and the unity, of Scripture. The Holy Spirit, who, by the inspiration of the biblical authors, embodied revelation in the Bible now assists the Church to remain rooted in the biblical message and to accommodate herself to the exigencies of each epoch by preaching, by the issuing of dogmatic statements, by the teaching of Church fathers, by iconography, and by liturgical worship.  Dogma lives in the stream of Tradition, and acts as its witness. It enables believers to accept the truth, as transmitted by living Tradition, and, in case of necessity, separates it from error. Formulated dogma becomes for believers the rule of faith, separating orthodoxy from heresy. The Orthodox Church does not exclude the possibility that she may proclaim fresh dogmatic definitions at some future ecumenical council, should the need to preserve the integrity and purity of faith require it. If, however, the Church extends the rule of faith by new definitions, this does not entail any augmentation or development of Tradition, but rather a deeper knowledge of the truth, within Tradition's stream.  The task of dogma, indeed, is not only to protect the truths of faith against error, or to define them in a conceptual manner (as an organic part of the Church's life). That task is also to furnish direction for spiritual and moral living.
For the existence of such a doctrinal development in the Church's history, the formation of dogma at the seven ecumenical Councils constitutes formidable evidence. More widely, Clement has put forward a tripartite scheme, in which Orthodoxy moves through three great periods of doctrinal development: the christological period, consisting of the first eight centuries of the Church's existence; the pneumatological period, running from Photius' council of 879-880 on the Filioque to the Constantinopolitan synods of 1341 and 1351 on Palamism; and lastly, the early modern and modern periods which are increasingly dominated by ecclesiological concerns. If in the first period the Christendom of both West and East was absorbed in the truth of the Incarnation and its saving effects, in the second the standpoint of Eastern theologians shifted in a way that went largely unrecognised in Latin Christendom. The new focus of attention on the truth of the Holy Spirit showed doctrinal development proceeding in terms of a different logic from what was happening in the West. Henceforth, Orthodox ecclesiology, the subject matter of the third phase, would be formed under the predominant influence of pneumatology. 
In terms of its revealed content, however, dogma remains, despite this, immutable: such is the teaching of the Fathers and the common consensus of the Church as a whole.  From Chalcedon onwards, the later ecumenical Councils insist that their decrees were no different from the rulings of previous councils, being re-statements by way of protecting truth against mis-statements.  Many Orthodox theologians are opposed to the idea that earlier dogmatic affirmations can include in tacit or implicit fashion hidden truths of faith that may be teased out by the later Church. They stress that dogma is simply the analysis of what has already (in the apostolic period) been uttered. The fullness of revealed truth is always present, they stress, in the Church, though in dogma that fullness is recapitulated as an expression of the Church's consciousness in a way particularly well-suited to dealing with the problems, and the errors, of some given time. Clement terms this the 'involution' of dogma, not its 'evolution'.  The concept of a vital, pre-conceptual state of knowledge is, such writers maintain, effectively indistinguishable from that of a sheer unconsciousness, and this ruptures the common consciousness of the truth of the Church. Consequently, an opinion considered false in one epoch is regarded as true in another - as actually transpired, they allege, in the case of the Immaculate Conception.
Despite Clement's attempt at a periodisation of the history of Orthodox doctrine which will give due weight to each of three successive epochs, far more characteristic of Orthodox theology at large is the immediate confronting of early tradition with modern thought. The Trinitarian and christological determinations of the first seven ecumenical councils are treated as a fundamental system of reference, to be used in developing responses to the questions left undiscussed at those councils - and above all, in the areas of anthropology and ecciesiology. The dogmatisation of the notion of a divine Person provides the warrant for Christian teaching on human personhood, while the doctrine of the Holy Trinity gives us a model to follow in speaking of the unity between local churches.  Orthodox theologians reach out immediately to the teaching of the Fathers, without the mediation of mediaeval and early modern theology, whereas, despite a succession of patristic revivals, Catholic divines must necessarily pay attention also to the high mediaeval doctors and to the fresh direction provided by the Council of Trent.
Occasionally, an Orthodox writer will go further and rejoice in the predominance of theologoumena over dogmas in Orthodoxy, as did the Russian priest-theologian S. B. Bulgakov. For Bulgakov, freedom is the nerve of theology, and diversity and multiplicity in theological expression constitutes Orthodoxy's beauty and power. Yet this point of view cannot be sundered from its context in Bulgakov's own controversial theological career, in which his personal development of the idea of Sophia, the Wisdom of God, as found in Scripture, the Fathers, and the Byzantine-Slav liturgy and its accompanying iconography, brought down on his head the condemnation of the Moscow Patriarchate as unwarranted innovation, and the sharp criticism of a number of his fellow-theologians as opening the door to a second Gnostic invasion of the Church.

16. This appendix is based on a report made for me by Father Wojciech Morawski, O.P.)., of the
Pontifical University of Saint Thomas, Rome. He draws attention to the studies on this subject of a Polish student
of Orthodox theology, Waclaw Hryniewicz, O.M.I., whose relevant writings are here given as a contribution to the
discovery by Western Catholic theology of the, so far, virtually unknown Polish theology of this century, something
which the freedoms now enjoyed by the Polish Church, and Polish society, will make possible. They are:
