I think what Fr. S. might be referring to is that political scandals, which The Dictator Pope exposes, are not the real issue; the real issue is doctrine.
.
It would be nice if he holds doctrine to be paramount, but he needs to SAY that ----- does he?
.
"...
fidelity to the Church's full tradition and the to Old Latin Mass” is all well and good, but it's possible to have that while being soft on doctrine!!
.
Fidelity to Sacred Tradition can be misunderstood! The Old Latin Mass isn't a silver bullet!
Annibale Bugnini celebrated the Old Latin Mass!
...he even wore a nice pectoral cross!
(But it appears to be missing the Corpus)
