It is not ex cathedra. Are you Roman Catholic?
Matter of faith or morals is always ex cathedra.
It doesn't have to be 'official statement' to say that he is speaking ex cathedra.
"Thinking about the laws recently adopted in Ukraine, I fear for the freedom of those who pray, because those who truly pray always pray for all. A person does not commit evil because of praying.
If someone commits evil against his people, he will be guilty for it, but he cannot have committed evil because he prayed. So let those who want to pray be allowed to pray in what they consider their church. Please, let no Christian church be abolished directly or indirectly. Churches are not to be touched!"
But it may be that we have different understanding of things.
For example , in Orthodox when one speaks about faith , he speaks in the name of the Cross.
"For we live by faith, not by sight."
I understand what you mean with opinion , but it is irrelevant since in his answer he speaks about matter of worship.
If by ex cathedra you mean only doctrine , then fine i accept it.
But there is another issue within that , and this is not the place to debate it.
