 According to M. G. Larsson, the reason why the Swedish core provinces had coexistence between paganism and Christianity throughout the 11th century was because there was a general support for the transition towards the new religion.However, the old pagan rites were important and central for legal processes and when someone questioned ancient practices, many newly Christianized Swedes could react strongly in support of paganism for a while.Larsson theorizes that, consequently, the vacillation between paganism and Christianity that is reported by the sagas and by Adam of Bremen was not very different from vacillations that appear in modern ideological shifts.
