Buddha teaching is not just theory. Theory has no use if there is no practical use.
It is better to understand single verse and put on practice than all those categories.
There is no different categories for SADDHA. This is confirm confidence in Buddha.
Also, As Buddha said in MN 95. No baseless faith.SN 48.9 wrote:And what is the faculty of faith?
Katamañca, bhikkhave, saddhindriyaṁ?
It’s when a noble disciple has faith in the Realized One’s awakening:
Idha, bhikkhave, ariyasāvako saddho hoti, saddahati tathāgatassa bodhiṁ:
‘That Blessed One is perfected, a fully awakened Buddha, accomplished in knowledge and conduct, holy, knower of the world, supreme guide for those who wish to train, teacher of gods and humans, awakened one, blessed.’
‘itipi so bhagavā arahaṁ sammāsambuddho vijjācaraṇasampanno sugato lokavidū anuttaro purisadammasārathi satthā devamanussānaṁ buddho bhagavā’ti—
This is called the faculty of faith.
Next time, please quote Sutta about SADDHA.MN 95 wrote:This being so, doesn’t the brahmins’ faith turn out to be baseless?”
nanu evaṁ sante brāhmaṇānaṁ amūlikā saddhā sampajjatī”ti?
“The brahmins don’t just honor this because of faith, but also because of oral transmission.”
