As an Eastern Orthodox Christian starting to dabble in this, I truly don't understand why witchcraft is considered "evil"

The Eastern Orthodox Church is extremely mystical and ritualistic in it's practice. We burn incense, prayer with prayer ropes, use holy water and make prostrations in front of icons.

I've been reading up on what witch craft truly is and to me it seems like a bunch of rituals that are done with intention to tap into a shortcut of psychology to manifest or make something happen. As long as it's done with good intentions, I don't see how Christians consider it "evil".

Here is my stance... If I acknowledge that God gave us the power to tap into our own psychology and manifest things, then how could this be bad?

Analogy:

• God created the soil, the seeds, and the rain.
• If you plant the seeds and water them (your ritual/intention), they grow.
• You aren't "stealing" power from God; you're just using the tools He left in the shed.

Catholics also practice things that seem a little bit "witchy". How about that prayer to Saint Antony when something is lost.

"Saint Antony, Saint Antony, Come on down, Something is lost that must be found", said 3xs.

Could i practice my Christianity and witchcraft at the same time? Also it seems like if it were called something else besides the word "witchcraft" , Christians might view it differently.
