For the early Christians, there was no difference between what today is often distinguished as orthodoxy and orthopraxis, as right doctrine and right action. Indeed, when this distinction is made, there generally is a suggestion that the word orthodoxy is to be disdained: those who hold fast to right doctrine are seen as people of narrow sympathy, rigid, potentially intolerant. In the final analysis, for those holding this rather critical view of orthodoxy everything depends on "right action", with doctrine regarded as something always open to further discussion. For those holding this view, the chief thing is the fruit doctrine produces, while the way that leads to our just action is a matter of indifference. Such a comparison would have been incomprehensible and unacceptable for those in the ancient Church, for they rightly understood the word "orthodoxy" not to mean "right doctrine" but to mean the authentic adoration and glorification of God. They were convinced that everything depended on being in the right relationship with God, on knowing what pleases him and what one can do to respond to him in the right way. For this reason, Israel loved the law: from it, they knew God’s will, they knew how to live justly and how to honour God in the right way: by acting in accord with his will, bringing order into the world, opening it to the transcendent.

Christ teaches how God is glorified, the world is made just.
