The reason I say this is because it doesn't sound like what a Coptic bishop would say. When Max Michel left and became his own patriarch, we didn't say, "It's just one person who left the Church." HH Pope Shenouda wrote an article asking Max Michel as a father to a son to come back to the Church that nursed him.
This isn't a pastoral response. It's about knowing how to respond to the media. Saying that these people are few, and they can leave the church sounds a lot like contradicting the idea that Christ would even give up His life for the one sheep that went astray. And this would be something Protestants would like to use as ammo against the Orthodox Church. "See" they'd say, "the Orthodox Church doesn't care about its people. Come to the real Christ-loving Church."
That's why I suspect a bunch of Protestants are trying to give a bad name to the Church by sourcing some "unnamed" bishop. It's quite odd that our bishops would fear to give their names when they make a statement.
I would expect a named bishop would say, "We will be very sad if these people left our Church. At the same, our hands our tied because we do not want to stray from the Orthodox faith."
