Mennonites affirm the traditional reading of John 1:1 as a statement of Jesus's full divinity. 'The Word was God' (kai theos ēn ho logos) asserts that the pre-incarnate Word possesses the full attributes of God. This reading is consistent with Trinitarian theology and the Mennonite Confession of Faith's affirmation of Jesus as fully divine.

The Anabaptist interpretation follows the patristic and Reformation exegesis of this passage. In the context of John's prologue, the identification of the Word (logos) with God (theos) establishes the basis for understanding Jesus's incarnation as God becoming human. This supports the Mennonite affirmation of both Jesus's pre-existence and his full humanity.
