So are you saying Saint Mark of Ephesus was wrong when he said that the Latins were heretics? Are you saying that the Oriental patriarchs were wrong in 1895 when they defines the latins as heretics?
The latins were condemned on many aspects by differents councils and others orthodox authorities. Here are some examples and the list is not complete :
Third ecumenica council
- These things having been read aloud, the holy Council then decreed that no one should be permitted to offer any different belief or faith, or in any case to write or compose any other, than the one defined by the Holy Fathers who convened in the city of Nicaea, with Holy Spirit. As for those who dare either to compose a different belief or faith, or to present one, or to offer one to those who wish to return to recognition of the truth, whether they be Greeks or Jews, or they be members of any heresy whatever, they, if Bishops or Clergymen, shall be deprived as Bishops of their Episcopate, and as Clergymen of their Clericate; but if they are Laymen, they shall be anathematized.
5th ecumenical council
The one worship of Christ.
To the Lord Jesus Christ as to one person, as the God-man it is fitting to give a single inseparable worship, both according to Divinity and according to Humanity, precisely because both natures are inseparably united in Him. The decree of the Fathers of the Fifth Ecumenical Council (the Ninth Canon against Heretics) reads: "If anyone shall take the expression, Christ ought to be worshipped in His two natures, in the sense that he wishes to introduce thus two adorations, the one in special relation to God the Word and the other as pertaining to the Man… and does not venerate, by one adoration, God the Word made man, together with His flesh, as the Holy Church has taught from the beginning: let him be anathema" (Eerdmans, Seven Ecumenical Councils, p. 314).
On the Latin cult of the "Heart of Jesus."
In connection with this decree of the Council it may be seen how out of harmony with the spirit and practice of the Church is the cult of the "sacred heart of Jesus" which has been introduced into the Roman Catholic Church. Although the above-cited decree of the Fifth Ecumenical Council touches only on the separate worship of the Divinity and the Humanity of the Saviour, it still indirectly tells us that in general the veneration and worship of Christ should be directed to Him as a whole and not to parts of His Being; it must be one. Even if by "heart" we should understand the Saviour’s love itself, still neither in the Old Testament nor in the New was there ever a custom to worship separately the love of God, or His wisdom, His creative or providential power, or His sanctity. All the more must one say this concerning the parts of His bodily nature. There is something unnatural in the separation of the heart from the general bodily nature of the Lord for the purpose of prayer, contrition and worship before Him. Even in the ordinary relationships of life, no matter how much a man might be attached to another — for example, a mother to a child — he would never refer his attachment to the heart of the beloved person, but will refer it to the given person as a whole.
Other example : Encyclical of the Oriental patriarchs of 1848
4. Of these heresies diffused, with what sufferings the LORD hath known, over a great part of the world, was formerly Arianism, and at present is the Papacy. This, too, as the former has become extinct, although now flourishing, shall not endure, but pass away and be cast down, and a great voice from heaven shall cry: It is cast down (Rev. xii. 10).
I could also talk about the Synodikon of the Holy Spirit which anathematizes the Filioquist and that is in use in the Greek church. Do not forget the Palamite council that condemned the catholic views on created energies...
