A lot of the old words which translate as witchcraft found in the old testament would be more accurately translated as poisoner. The Grimoire of Honorius was written by a pope. Despite being a religion which claims to have only one truth, Christianity has a lot of variation inside of it. Depending on how you define magic, even a prayer could count as a spell (I define it this way). Also, many Christians practice ignorantly a form of channeling. They try to make themselves "Clean, empty vessels" so the Holy Spirit, the Christian equivalent of the Crone, can empower them and work through them. Even outside of the Catholicism and similar denominations who rampantly call of their honoured dead, Christianity has a good deal of magic or witchcraft (I don't see a difference) in it. I am not a Christian, but I used to be. I didn't leave because of my magical practices, I left for personal reasons. Magic is not a religion, it is a craft to be worked by any who know it of any faith, or even those with no faith.
Many people practice both. Some aspects of the religions Apple each other, but when it comes down to it its up to you what you want to believe in and practice. You don't have to follow every aspect; Just practice what you like from both.
From my bringing up, the church is against any form of otherworldly contact. Summoning, divination those are the biggest no-nos according to the doctrine. It is said that all sorcerers etc be cast out in most iterations of the bible. The only way one is allowed to perform these acts is if God allowed it of them Himself. That's as much as I can say myself. But to answer your main question, most Christian, not nesesarily catholic, but most Christian religions prohibit it. Some of these are Roman Catholic, Anglican, Pentecostal and Evangelic an.
Christianty and Witchcraft are lot possible. There with different extremely. Christianty is now my chosen path, bit in my opinion the two from with paths I have done would be set you for failure.
Witchcraft is a Ahmed in this religion. Meaning that if together you practiced your going for hell. While I don't judge, think about it here.
Gnostics Practiced Magick thousands of years ago
One of the Oldest Grimores was written by a Catholic Pope
Hoodoo,Santeria,Folk Magick,Italian spell craft all come from Catholic Backgrounds.Church is the same as many occult groups
They were robes,wear charms,light candles and incense
Vibrate words raise energy,Sing etc,Christian faiths are all about Magick even if they don't realize it...I do
I love my Roman Catholic Faith and I love Magick
Luckily I had a roommate who taught me about Hoodoo
It was the path that gave me the change to mix the two worlds peacefully
