In this article, the author provides a simplified understanding of christology on the subject of the divinity and humanity of Christ as expressed by the Council of Chalcedon in 451.

Throughout the history of the church, heretics often protested against orthodox confessions on the ground of the so-called "non-scriptural language" of the orthodox creed. They pointed out that phrases such as “of one essence with the Father,” and “one substance with the Father” were not to be found in Scripture. Heretics often used the argument “no creed but the Bible” precisely so that they could use biblical language to evade biblical truth.
