One of the great things about Unitarianism is that ability to say 'I don't know'...even to say I don't care (in the sense that it isn't an important issue). the church generally has spent centuries trying to provide answers, such as limbo to the question of what happens to unbaptised babies, only to later find another set of answers because they can't admit that in reality...they don't know...but are afraid of admitting it.
