A visible church is united as one with Christ as the head.  How does our reaction to anger disrupt that unity and grieve the Holy Spirit?

Ephesians4:30-5:2 (Evangelical Heritage Version)

30Do not grieve the Holy Spirit of God, with whom you were sealed for the day of redemption. 31Get rid of every kind of bitterness, rage, anger, quarreling, and slander, along with every kind of malice. 32Instead, be kind and compassionate to one another, forgiving one other, just as God in Christ has forgiven us. 5:1Therefore, be imitators of God as his dearly loved children. 2And walk in love, just as Christ loved us and gave himself for us, as a fragrant offering and sacrifice to God.
