The Session of Christ or heavenly session is a Christian doctrine stating that Jesus Christ is seated at the right hand of God the Father in Heaven—the word "session" is an archaic noun meaning "sitting". Although the word formerly meant "the act of sitting down", its meaning is somewhat broader in current English usage, and is used to refer to a sitting for various reasons, such as a teaching session, or a court or council being in session. The New Testament also depicts Jesus as standing and walking in Heaven, but the Session of Christ has special theological significance because of its connection to the role of Christ as King. The Session of Christ is one of the doctrines specifically mentioned in the Apostles' Creed, where "sitteth on the right hand of God the Father Almighty" immediately follows the statement of the Ascension.
