No, Scott Hahn’s interpretation of the Book of Revelations is in line with Catholic thought. The connection between the Mass and the Book of Revelations is clear if you’ve at all read Revelations and although many Catholics are unaware of this strong and very important connection, it is well known in the eastern Church.
The Book of Revelations, unlike it is popularly know to be, is actually about the past, the present, and the future (not just the future). Some parts of it talk about Mary, the birth of Jesus, the rebellion of the angels, and other past events. Some of it was future prophesy, but has already happened and is therefore now past, for example the sack of Jerusalem and the 144,000 Christians saved. And now we have the present, the Mass. The Book of Revelations talks about how Heaven is, and what you’ll notice is that it’s a lot like Mass. That’s because Mass IS Heaven on Earth. Some would also make the claim that some of the endtime prophesies are being fullfilled in this day of time. Will Catholics are not really bound to a teaching on this in the present, it should be known people have been claiming that the endtimes prophesies were happening for quite some time now, famously with Hitler as the anti-Christ (obviously untrue). Also Jesus tells us that these things will happen like a thief in a night, we won’t know when, but, He says, we should be ready always.
I also recommend reading The Lamb’s Supper by Scott Hahn as someone already recommended, because you can’t begin to understand Revelations in a forum post, it requires much more thought.
But as for your question: much of Revelations isn’t bound to a certain teaching or interpretation although there is the norm of Catholic thought. For example, the beasts in Revelation are more commonly thought to be metaphors. What I mean is that they exist, but they might not actually look like how they are described, it could instead be a metaphor of the disgust of their ‘soul’. You’ll also find that the beasts in Revelation and pretty much everything Satan does in it is all an attempt to mock God. You’ll understand more with reading that book so I really recommend it.
