Wha? No, no. I love daimons and materia magicae but none are absolutely required to do magic.
We can do it preferably well with just our imagination. Lynne McTaggart's Power of Eight demonstrates the amazing effects of focused group workings. Grim magicians and witches just like to include minds that don't have human bodies.
The current academic consensus indicates Western Magic comes to us originally from the Greco-Egyptian sorcerers (by way of Byzantium to Venice, London, New York, Houston, more, and all points south). If you read the PGM (Greek Magical Papyri), magicians tend to keep the deities on very tight leashes. That is totally valid approach reflected in many of the grimoires (the most extreme being the infamous Chain Curse in the Lesser Key, which is not a grim I use) , but it's not the only way.
In Vodou, the Lwa (who are not deities like most think of them) are not worshiped, but they are honored and venerated. Practitioners 'serve the spirits' so the spirits will serve them. It is a relationship of familial love. Vodou says "All sprits bow before God." so in "worshiping God" (fill in your own name for The Mystery) becomes another way to relating through a shared experience of beauty, kindess, compasssion, and chairty. It's a way to structure social interaction with other humans and The Invisibles, not about the worship per se.
(Again, not preaching here. Fill in with your own value system as you wish. Just know you will meet others, with and without bodies, who share those values, and you will all embody them more and more over time, as you focus on and celebrate them.)
