What is the difference between exorcism prayer and deliverance prayer for demons?

Deliverance prayer asks God for help against spiritual oppression, can be said by anyone, and focuses on a broad range of issues like temptation, sin, or confusion. Exorcism is a specific, formal rite to expel a demon from a person believed to be possessed, which can only be performed by a priest with a bishop's delegated authority, and involves commanding the demon to leave. 

Deliverance prayer

• Purpose: To ask God for help and freedom from spiritual problems, oppression, and negative influences.

• Authority: Can be prayed by any believer in Jesus Christ.

• Nature: A prayer asking for God's assistance, using God's authority to overcome evil.

• Examples: Prayers like the Lord's Prayer or the St. Michael's Prayer are considered deliverance prayers, and people can also pray their own personalized prayers for freedom from spiritual bonds and oppression. 

Exorcism

• Purpose: To formally and ritually expel an evil spirit from a person believed to be possessed.

• Authority: Performed by a priest or bishop who has been delegated this authority by the Church.

• Nature: A command to the demon to leave in the name of Jesus Christ, following a specific ritual and set of prayers established by the church.

• Scope: Reserved for the most severe cases of demonic influence, known as possession. 

In essence, while both types of prayers seek freedom from demonic influence, deliverance prayers are a broader category accessible to all believers for various forms of spiritual oppression, whereas exorcism prayers are a specialized, formal rite reserved for severe cases of demonic possession and performed by authorized clergy
