In the West, there was (is?) a qualitative distinction between monastic consecration and marriage.
Some try to apply that distinction to the clerical / laical relationship due to the idea of the ontological change that occurs at ordination.
An orthodox priest told me that they did not believe in an ontological change at ordination, but a "functional" change in how service in the Church is performed.

I would to clarify and understand this. Am I misunderstanding? How are these two relationships understood in the byzantine churches?
Monastic vs Marriage? Clerical vs. laity?

Thanks.
