Paul Chen:

For Christianity between the 1st and the 4th century, I can do no better than to reiterate the fourth Gospel, the first Johannine epistle, the Apocalyse, and On The Incarnation by St. Athanasius.  Why should we assume that the 5th century bishops at Chalcedon believed anything different than Christians before them, when the Definition of Faith they formulated drew upon the previous five hundred years of tradition?

A closer study of history and the church’s doctrinal development is in order before we just wave off Christ’s divinity.  There is a reason that Christians believed this before.  They were not stupid and the Holy Spirit did not leave them in the dark.
