Christians are not allowed to practise magic. It is forbidden in the Bible:
Exodus 22:18 King James Version (KJV):
Thou shalt not suffer a witch to live.
Leviticus 17:7:
So they shall no more sacrifice their sacrifices to goat demons, after whom they whore. This shall be a statute forever for them throughout their generations.
1 Timothy 4:1:
Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
2 Kings 17:14-17:
They went after false idols and became false, and they followed the nations that were around them, concerning whom the Lord had commanded them that they should not do like them. And they abandoned all the commandments of the Lord their God, and made for themselves metal images of two calves; and they made an Asherah and worshiped all the host of heaven and served Baal. And they burned their sons and their daughters as offerings and used divination and omens and sold themselves to do evil in the sight of the Lord, provoking him to anger.
