Let me give thee this charge also. Study our teachings and keep them for ever. Think not that they are the ordinary homilies; for though they also are good and trustworthy, yet if we should neglect them to-day we may study them to-morrow. But if the teaching concerning the laver of regeneration delivered in a consecutive course be neglected to-day, when shall it be made right? Suppose it is the season for planting trees: if we do not dig, and dig deep, when else can that be planted rightly which has once been planted ill? Suppose, pray, that the Catechising is a kind of building: if we do not bind the house together by regular bonds in the building, lest some gap be found, and the building become unsound, even our former labour is of no use. But stone must follow stone by course, and corner match with corner, and by our smoothing off inequalities the building must thus rise evenly. In like manner we are bringing to thee stones, as it were, of knowledge. Thou must hear concerning the living God, thou must hear of Judgment, must hear of Christ, and of the Resurrection. And many things there are to be discussed in succession, which though now dropped one by one are afterwards to be presented in harmonious connexion. But unless thou fit them together in the one whole, and remember what is first, and what is second, the builder may build, but thou wilt find the building unsound.

The Holy Canons
Liturgics by Archbishop Averky
If any one desire to fulfill his duty of obedience to the Church, how may he learn what she requires of her children?
This may be learned from holy Scripture, from the canons of the holy Apostles, the holy œcumenical and provincial Councils, and the holy Fathers, and from the books of Ecclesiastical Rules and Rubrics.

Door to Paradise by Monk John Marler
Do you think that you can stand and live if you withdraw from the Church, building for yourself other homes and a different dwelling, when it is said to Rahab, in whom was prefigured the Church, “Thy father, and thy mother, and thy brethren, and all the house of thy father, thou shalt gather unto thee into thine house; and it shall come to pass, whosoever shall go abroad beyond the door of thine house, his blood shall be upon his own head?”

The Heresy of Ecumenism
St Philaret of New York and the Heresy of Ecumenism by Vladimir Moss
Those who attack the Church of Christ by teaching that Christ’s Church is divided into so-called “branches” which differ in doctrine and way of life, or that the Church does not exist visibly, but will be formed in the future when all “branches” or sects or denominations, and even religions will be united into one body; and who do not distinguish the priesthood and mysteries of the Church from those of the heretics, but say that the baptism and eucharist of heretics is effectual for salvation; therefore, to those who knowingly have communion with these aforementioned heretics or who advocate, disseminate, or defend their new heresy of Ecumenism under the pretext of brotherly love or the supposed unification of separated Christians, Anathema!
The Heresy of Cyprianism (Crypto-Ecumenism)
Cyprianism: Crypto-Ecumenism – The Heresy of Our Days by Protopresbyter Victor Melehov
We ordain that a bishop or presbyter who has admitted the baptism or sacrifice of heretics be deposed. For what concord hath Christ with Belial, or what part hath a believer with an infidel?
– Apostolic Canon 46
The Heresy of Sergianism
About the “Moscow Patriarchate” by Archbishop Averky
Sergianism as an Ecclesiological Heresy by Vladimir Moss
Being in all his activity an anti-church heretic, as transforming the Holy Orthodox Church from the house of the grace-filled salvation of believers into a graceless, carnal organization deprived of the spirit of life, Metropolitan Sergius has at the same time, through his conscious renunciation of the truth and in his mindless betrayal of Christ, become an open apostate from God the Truth.
