Quote:
But if I cast out devils by the Spirit of God,
then the kingdom of God is come unto you.
Or else how can one enter into a strong man's house,
and spoil his goods, except he first bind the strong man?
and then he will spoil his house.
Matthew 12:28-29 KJV

But if I with the finger of God cast out devils,
no doubt the kingdom of God is come upon you.
When a strong man armed keepeth his palace,
his goods are in peace:
But when a stronger than he shall come upon him,
and overcome him,
he taketh from him all his armour wherein he trusted,
and divideth his spoils.
Luke 11:20-22
Tan's fundamentalist error (that demons are supposedly not fallen angels) fails to account for Christ's use of the word "devils" in Matthew's & Luke's version of the parable of the binding of the strong man.

Satan is one of the fallen angels.
Satan is one of the devils. (Revelation 12:9,12; 20:2,10)

Christ was casting out devils.
Therefore Christ was casting out fallen angels.

The parable plainly identifies that Satan was the strong man,
that the palace was Satan's kingdom
and the strong man's palace is plundered by Christ,
because Christ has already bound the palace's strong man.

"How can Satan cast out Satan?
And if a kingdom be divided against itself,
that kingdom cannot stand.
And if a house be divided against itself,
that house cannot stand.
And if Satan rise up against himself, and be divided,
he cannot stand, but hath an end.
No man can enter into a strong man's house,
and spoil his goods,
except he will first bind the strong man;
and then he will spoil his house."
Mark 3:23-27 KJV
