Unitarianism

I'm studying Trinitarianism right now, which has brought me into contact with Unitarianism. I had come across the term Socinian several times this semester, but I hadn't been motivated enough to follow up on it. But then I hit the term Latitudinarian and I knew it was time to stop being lazy. Now I know that Fausto Paolo Sozzini was a 16th century Italian theologian whose doctrines were largely responsible for the Unitarian movement in Europe.

What I already knew was that the Unitarian movement merged with the Universalist movement, and created a church that is about as Progressive as you can get. I won't elaborate more on that here. The thing I keep getting wrapped around the axle about is if you believe that the bible isn't infallible and that all religions have value, what is the motivation to devote yourself to a church? I don't have an answer to that yet, but I read two articles from Unitarian ministers that piqued my interest: Why You Should Not Be A Unitarian Universalist by Rev. Dr. Tony Larsen, and Why Agnostics Go to Church
by Rev. J. Mark Worth. That is all.
