In the book The ONENESS Of GOD, the well-respected author David Bernard pinpoints the observable distinction between God the Father and the Son of God. “Father refers to Deity alone while Son of God refers to Deity as incarnated into humanity.” Among the Oneness movement, there is a network of individuals who have spent many hours revisiting the core fundaments of Modalism in order to expound on the Son’s identity, nature, and corporeal existence. Decoding Precepts of Oneness Theology is the product of one writer's investigation. More than a simple formula of “Spirit versus flesh,” author Andrew M. Denny pinpoints the observable distinction between Father and Son in the most descriptive terms necessary to further understand the humanity of the Son of God as described by His witnesses. While some aspects may not entirely agree with traditional Modalism (as defined historically), his focus will be to evaluate the vocabulary of the early church in comparison with our modern dialect.
