When you consider the fact that various factions adopt things like dispensationalism and the Rapture based on the teaching of an individual in spite of such things having never been taught prior to that individual it's clear that most Protestant factions do indeed have the equivalent of Talmudic teaching that they consider superior to Scripture.
Not really surprising given the fact that fundamental to all Protestant doctrine is the assertion that the Holy Spirit is imperfect and implicit in that assertion is the replacement of the Holy Spirit with the Self and Self Alone
Your last paragraph nails it.
