There is more about the Scripture being the true test of Truth than:
Mariology
infant baptism
Popehood or any man more holy than another
a successorship for the Apostles
required celibacy for priests
oh the list goes on and on if you demand explicitly . let the rule go BOTH ways.
I would dispute infant baptism on your list. From my study, there is sufficient logical and Scriptural support for that, at least.
But other than that, spot on.
And as long as you’re not trying to argue Anabaptism I don’t think it’s worth the argument at this time in this place.
