Most Reverend James Atkinson Wake, Archbishop of Cambridge. Secretary of Doctrine and Faith Worldwide-Patriarchate.

MY ROLE AS SECRETARY OF DOCTRINE AND FAITH:

My duty as the Secretary of Doctrine and Faith is to promote and safeguard the Doctrine on the Faith and morals throughout the Catholic Apostolic world: for this reason everything which in any way touches such matter falls within its competence."

REGULATIONS FOR DOCTRINAL EXAMINATION:

Art. I. The Secretary of Doctrine and Faith has the function of promoting and safeguarding doctrine on faith and morals throughout the Catholic world. In accomplishing this purpose, it renders a service to the truth, by protecting the right of the People of God to receive the Gospel message in its purity and entirety. Therefore, in order that faith and morals not be harmed by errors however disseminated, it also has the duty of examining writings and opinions which appear contrary to correct faith or dangerous.

Art. II. This fundamental pastoral responsibility concerns all the pastors of the Church, who have the duty and the right to exercise vigilance, whether individually or gathered in particular Councils or Episcopal Conferences, in order that the faith and morals of the members of the faithful entrusted to their care not suffer harm. To this end, they can also be served by Doctrinal Commissions, institutionalized consultative bodies which assist Episcopal Conferences and individual Bishops in their solicitude for the doctrine of the faith.

The principle remains, however, that the Patriarch can always intervene and, as a rule, does so when the influence of a publication exceeds the boundaries of an individual Episcopal Conference, or when the danger to the faith is particularly grave. In such cases, the Secretary of Doctrine and Faith uses certain procedures. 

Fulfilling the function of promoting doctrine, it fosters studies to promote the understanding of Catholic teaching and also studies new questions that arise from developments in science and human culture. The Secretary provides help and guidance to bishops around the world in their role as teachers of the Catholic faith with directives from the Patriarchate
The "DOMINUS IESUS" paragraph 17, states:
Therefore, there exists a single Church of Christ, which subsists in the Catholic Church, governed by the Successor of Peter and by the Bishops in communion with him
The  Churches which, while not existing in perfect communion with the Roman Catholic Church, remain united to her by means of the closest bonds, that is, by apostolic succession and a valid Eucharist, are true particular Churches
Therefore, the Church of Christ is present and operative also in these Churches, even though they lack full communion with the Roman Catholic Church, since they do not accept the Catholic doctrine of the Primacy.

BY WHO'S AUTHORITY IS DOMINUS IESUS PLACED.

WHAT DOES IT MEAN.

WHAT IS APOSTOLIC SUCCESSION.

Apostolic Succession, the doctrine asserting that the chosen successors of the Apostles enjoyed through God's grace the same authority, power, and responsibility as was conferred upon the apostles by Jesus.
Therefore present-day bishops, as the successors of previous bishops, going back to the apostles, have this power by virtue of this unbroken chain. For the Catholic churches, this link with the apostles is what guarantees them their authority in matters of faith, morals, and the valid administration of sacraments. Essential to maintaining the apostolic succession is the right of consecration of bishops, and ordaining of priests and deacons.
