By using the REAL TEST of what was believed in Bible times, you cannot possibly claim nobody believed in the Trinity until the 4th century. You have to ignore ALL the supporting Scripture as well as the writings of Christian leaders prior to then upon which the Nicean Creed - which formalized the definition of the Trinity in a succinct manner - was based on. C'mon...this was not something a group of drunks invented to fool Christians! And I don't just believe a "4th century construct", I believe because God revealed its truth in His word. We are composed of body, soul and spirit - three, yet still one person. We were created in the image of God who is Father, Son and Holy Spirit - three, yet still one God.
I'm done arguing with you as well. I stated why I believe in the Trinity and you said why you don't. Each person should make up his/her mind based upon the evidence and as God leads them.
Where, specifically, is THIS written down?
Just because there is NO evidence of this 'unbelief'; doesn't mean you can claim there was NONE!
