Christian and pagan

Something I have been researching actually.the term pagan is a lot more broad than christianity so I will assume you mean pagan witchcraft...correct me if I am wrong. So far what I found, Christianity according to the bible advises you to drop anything that can feed the ego or the flesh and depend on God and community, while most pagan/witch beliefs (even the lighter beliefs) advises you to do whatever you want to and (usually) not harm others and to rely on yourself. This contradiction alone can interfere with your spells and intent sense each are powerful belief systems and from my understanding intent is a big deal with magic. Christianity is a lot more open while pagan witchcraft is often exclusive or find out for yourself and "look within" in case you have not noticed the responses in the forums. Even new age pagans advise you fully abandon any control system to be "awakened". you probably can still mix both but I think most people would have to be really strong in their intent. I would tell you how I would think to do it but you would have to talk to a person who actually practices both at the same time. Hope that helps

From obsessive amount of spiritual research and Christian experience.

I would have to say yes and no. On the pagan side, unless you follow a very specific and exclusive path, then yes you can. I honestly don't think the gods are that jealous.
On the Christian side, they will immediately tell you no. They will claim your pagan gods are idols, which is a sin, although many of them are monotheists and have never worshipped multiple gods. Therefore, they have absolutely no experience with the concept of lesser gods or goddesses. An idol, by definition, is something that you make more important than the Christian god. A lesser god or goddess is not an idol unless you make them more important in your life than the Christian god. Keep in mind both sides will give you trouble for your path, but you can make it possible if you want to.

Also, if you want to practice witchcraft, they will also tell you it is a sin, so if you want to be a pagan and Christian, you may well have to omit that practice. Now some will also tell you that any pagan god ever is a demon in disguise. I will tell you from the deepest, sincerest part of my heart that I think this is a lie. It's really up to you and your discernment though.
