Harmony

Extremists will ignore the most necessary that God desires and break God's spiritual harmony. If you look back that Jesus rebuked religious leaders who had extreme doctrines that intimindated others who don't follow their rules. Christian faith is not to manipulate and intimidate people with doctrines but rather allow the Holy Spirit to do the work in convicting people's hearts. We are not to persuade people to follow certain extremist views of doctrines (that each of us hold) because only God can take care of that based on each individual as the Holy Spirit convicts their hearts.
