My views have been fairly clearly stated:
Aerial Toll Houses and similar gnostic views were known in the Early Church as it was a widespread cultural belief of the time - it never became a formal Church teaching despite this.
So you may personally believe in this silliness (now resurrected by Victorian Spiritualism and popular TV shows) if you wish - it has not been formally condemned as I say. The Church only tends to address/condemn such views when they become widespread.
However it cannot be called a Church teaching. It is over the top to try and suggest it is.
Saints are canonised for their holiness and charity not their writings.
Priests are fallible and idiosyncratic like us laity. If you look specifically for a priest to back your own “Catholic” views on angels, demons, superstition, the death of Mary, the Pope being used by Satan, the Vatican has fallen etc…I am sure you will find one online somewhere.
Gnosticism is a heresy and a distraction from the right path to God. The sorts of belief’s mentioned here were part of their “corpus”. While not specifically condemned the movement was. That should give loyal Catholics pause for thought re these fancies of souls needing to work out their “purgatory” on earth and in the places where they have “unfinished business.”
That is also a belief of Victorian Spiritualism. This has also been condemned by the Church.
It is alive and well in the “folklore” of the less well educated in the USA - including Catholics it seems.
