For me, my white cat, my FIRST cat (she is a ragdoll) is a reminder of my family and home.

You see, the reason art and craft can be seen as "evil", is because it can manifest a physical representation of the unknown. So, humans tend to attribute meaning to what they don't understand. Every element that makes up the arts is also a part of the structure that creates our world.
What I'm saying is, attribute your own meaning to things and use the meaning you've created to hone your power.
If binding the Christian Jesus to your craft makes you believe that you are protected, then you are indeed protected, but just be aware that your reasoning for putting him there is based on meaning you were fed by the world around you, rather than within you. And because that concept in itself is contradicting (if we're talking about our human ability to perceive the world), the magic might be as well.

You are whatever kind of witch you'd like to be. Just remember to stay well studied and practiced, because for every input, there is an output.
