[Petrosius]

There is absolutely nothing any priest or other spiritual father can do to transmit or not transmit God’s uncreated energies, so he can have no effect on any sacrament.

Sorry, but this contradicts what our Lord said. Remember that our Lord said that the priest has the power to retains sin as well as forgive. Additionally, is not the action of the priest/bishop necessary for the sacraments of the Eucharist and ordination to Holy Orders?

[Kolokotronis]

“Additionally, is not the action of the priest/bishop necessary for the sacraments of the Eucharist and ordination to Holy Orders?”

Of course, and for Marriage and Unction and Chrismation, too...but no ordination is necessary to be a confessor in Orthodoxy.
