The lines are from the Latin Rite of Exorcism. (English translation.)

Anderson: A dash of holy water and a key passage from the Rite of Exorcism should do the trick…Heinkel, can you provide the ritual responses?

Heinkel: Are you kidding? I could do an exorcism in my sleep.

Anderson: Good. Ecce crucem dómini fúgite, partes advérsae.

Heinkel: Vicit leo de tribu juda, radix David.

Anderson: Dómine exaudi oratiónem meam.

Heinkel: Et clamor meus ad te véniat.

Anderson: Dóminis vobíscum.

Heinkel: Et cum spírito tuo.
