Yes, that is what Catholics always say.
Narses and his YOPIOS comes to mind.
But believers are not left to interpret Scripture with frail human understanding. We have been born again and filled with the Spirit who rightly discerns its meaning for us.
Anyone can quote Scripture but not everyone, outside of the Spirit, can understand it.
The author of this article has decided he is filled with the correct Spirit. T is his own opinion that he is filled with the correct spirit. It is his own determination that he can understand scripture and the rest of us can’t.
He could very well be wrong about his own understanding and has no definitive proof, other than his own feeling that he is born again and filled with the spirit. Catholics are born again and filled with the spirit also.
Subjective relativism at its finest.
