Update: I wish to question the endorsement of hierarchies in this article. Yes, Jesus is recorded as having named 12 apostles, who would in future judge the 12 tribes of Israel. But is any earthly hierarchy given by Jesus? Instead, Jesus can be understood to prohibit hierarchy in Matthew 23. Likewise, in John 21, the commission to Peter can be read without any permission for a hierarchy (authorities within the Church/Flock of Christ). This is because the two Ancient Greek verbs used there, bosko and poimaino, had several senses each, such as "feed" and "tend" respectively.

One divine system could be called sanctification for glorification for salvation.
(1) Christians are enabled by God to do good works (Ephesians 2:10; 2 Corinthians 9:8).
(2) Those good works cause other people to glorify God (Matthew 5:16).
(3) People who glorify God take one key step closer to receiving God's salvation (Acts 10:1-48; 1 Corinthians 14:19-25; 1 Peter 2:12).
Bad theology works against these systems. Consider, for example, the theological mistake that says—in contradiction to Matthew 5:16 and James 2:14-26—that Christians do not need to do good works because Christ's righteousness is counted as theirs. Such bad theology will disrupt the system of sanctification for glorification for salvation.
Or consider another divine system described in the New Testament: it could be called chastizement for sanctification, witness and unity.
(1) God sends illnesses on Christians to save them from condemnation (1 Corinthians 11:30-32).
(2) If a Christian has an illness (James 5:14-18), he or she should
- confess his or her sins to another Christian;
and
- have the elders of the church pray for them and anoint them with oil.
What does such a system achieve?
(A) Sanctification.
Christians are led away from sinful behaviors.
(B) Witnesses to God.
Being healed by God provides proof to unbelievers of God's existence and character, and builds up the faith of Christians.
(C) Church-building.
Healing requires a church with elders. This gives a powerful incentive for Christians to build up and care for churches (rather than trying to practice Christianity independently).
Bad theology undermines this system, for example
- when preachers and pastors are teaching that God does not send illnesses on Christians;
- when preachers and pastors are teaching that Christians with illnesses do not need to confess their sins;
- when preachers and pastors fail to teach that God demands holiness from His children (1 Peter 1:13-20).
