from "Misrepresenting Witness Lee’s Critique of Christianity ".
To say that something is degraded simply means that it has fallen below its ordinary standards or that it has negatively changed in its function and structure.17 According to Witness Lee’s teaching in Practice, the system of Christianity is degraded in its standards, function, and structure because it has developed “formalities and rituals,” “regulations and unscriptural practices,” “hierarchy” with “ambition” for position, and the “clergy-laity system.” Today’s Christianity is also full of divisions.18 It is these negative matters that kill the organic function of the members of the Body of Christ.

This degraded religious system [of Christianity] takes the natural, human, traditional, cultural, and religious way. Humanly speaking, religion is a good thing, but spiritually speaking it is something against God's economy. God does not want a religion, but He surely wants to see His economy accomplished. We are not here for religion but for God's economy, which is to propagate His completed Christ to produce the church as the Body of such a Christ.

The church includes all those who share the common faith that saves us, the one faith spoken of in Ephesians 4:5. This faith is held in common by all who are saved (2 Pet. 1:1). This faith causes the believers to be one and does not divide them. Any creed or system of teaching that goes beyond the common faith divides the believers.
