EO on Communion with Heretics/Schismatics

According to the canons of the Eastern Orthodox faith, no one can have communion with heretics or schismatics and still remain in good standing with the Church. This applies to the clergy as well:

Canon XXXII of the council of Laodicea states:

Canon XXXIII of the council of Laodicea states:

Canon X of the Holy Apostles states:

Note: What is meant by an “excommunicated person,” is anyone that is barred from communion, not just those who used to be in communion.

Canon XLIV of the Holy Apostles states:

Canon LXV of the Holy Apostles states:

(Why are Orthodox Christians Forbidden to Pray with the Heretic; emphasis mine)

This, therefore, means all of the Patriarchs and Bishops that have and continue to work with or bless schismatics and heretics such as Muslims, Jews, Hindus, Protestants, etc., are in grave sin and must be defrocked and removed from the clergy. This especially applies to all of the EO hierarchs, particularly from those of the Constantinople patriarchate that frequently attend Catholic masses to show their support to the Catholic Church, since EO considers the Catholic Church to be heretical and in schism.

Moreover, any EO who joins with them or takes the sacraments from them is implicit in their sins and must either repent or be removed from the Church.
