The Pope may desire reunion for the best of reasons. But the problem is Rome's modernism which departs radically from the old Faith. It is indisputable that central dogmas of Catholicism are routinely denied. This is a huge problem that only God apparently will be able to fix. Meanwhile SSPX has taken as its mission the preservation of the Faith as it had been practiced for two thousand years before the last council. It is what all Catholics once were--before the modernist heresies took hold.

[ThomasMore]

It is indisputable that central dogmas of Catholicism are routinely denied.

[Polycarp]

central dogmas of Catholicism are routinely denied

Name one central dogma of Catholicism that the Catechism denies.
