Castiel being exorcised

Castiel almost being banished from his vessel.

The Angelic Exorcism is a rare type of exorcism that so far only the white eyed demon Alastair has shown knowledge of. He nearly sent Castiel back to heaven.

Overview

It works exactly like a demonic Exorcism and Angel banishing sigil but it is implied that its effects are much more potent, as an Angel Banishing Sigil only banishes an angel far away from its initial location on Earth and the angel remains in his or her vessel, whereas the exorcism ejects the angel from its vessel and banishes it back to Heaven.

Considering that Alastair considered banishing an angel to Heaven as an alternative to killing them off ("I really wish I knew how to kill you, when all I can do is send you back to Heaven."), it is likely that the angel would be unable to return to Earth immediately, if at all.

The verses used in the spell are in Latin:

Omnipotentis Dei potestatem invoco
Omnipotentis Dei potestatem invoco
Ab orbe terra
Hunc angelum omne obsequendum
Domine expuet
Domine expuet
Ut deum ad empyreum remittat

English Translation:

"I invoke the almighty power of God
I invoke the almighty power of God
From over the Earth
This Angel obeys all [His orders]
The Lord has expelled him
The Lord has expelled him
And in the same way, God sends him back to Empyrean."
