Met. Valentine has already been deposed in heaven because of his lawlessness. The canons he broke are numerous.
Breaking only one is actually enough. He accepted Michael Graves from Haiti and 185 parishioners with him unbaptized. Micahel Graves himself admits that he pours on people and does not immerse them. I talked on the phone with a person in Florida who has met Michael Graves and he confirmed all the above.
Apostolic Canon 46 is enough to depose Met. Valentine
APOSTOLIC CANON XLVI
We order any Bishop or Presbyter, that has accepted any heretic’s baptism or sacrifice be deposed; for “what consonance has Christ with Belial? 66 or what part has the believer with an unbeliever?”
In addition this canon puts the last nail to it:
APOSTOLIC CANON L
If any Bishop or Presbyter does not perform three immersions in making one baptism, but only a single immersion that given into the death of the Lord, let him be deposed . For the Lord did not say, Baptize into my death, but, “Go you and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit” (Matt. 28:19).
The root of the problem is that Met. VAlentine and his faction do not believe in the canons. They are of a different faith than the Orthodox.
For them the Canons are optional. For Abp. Gregory they are the words of life and the commandments of God.
It is that simple.
We listen to Christ our Savior: "If ye love me, keep my commandments". (John 14:15)
