I always love the "not part of official teaching". So it's unofficial teaching? And WHAT is that?
One way to look at it is that if you can be tried for heresy for it, it's official.
If not, well then, it's theological speculation.
"I always love the "not part of official teaching". So it's unofficial teaching? And WHAT is that?"
It was debated for centuries, but never declared official teaching through ex-cathedra statement by the pope or confirmed in vatican approved church councils.
