We must be guided by the Dogmas and the canons of the Church
Yep. Does this include the 1st Apostolic Canon though?
In the normal course of events yes however...
Orthodox Christian Education Society: The Rudder, Chicago, 1957, p. 4, lines 11-13 "The Apostolic Injunctions (Book VIII,
chapter 27), on the other hand, commands that anyone ordained by a single
bishop be deposed from office along with the one who ordained him, EXCEPT
ONLY IN CASE OF PERSECUTION or some other impediment by reason whereof a
number of bishops cannot get together and he had to be ordained by one
alone, just as was Siderius ordained bishop of Palaibisca, according to
Synesius, not by three but by one bishop, Philo."
