You can hang out with your friend, just keep in mind 2 important things:
1. You need to make sure you're cleaning and protecting your aura before and after you hang out at the church.
And 2. I don't know how close you are with your friend, but keep in mind how religious she is and if in the long run, this is a friend you want to keep. Those who are on the "religious side" tend to antagonize their Satanist 'friends' over time. It might not be the case now but it can amplify over time. I also don't know if this is your only close friend or not but with spiritual aggression, you'll definitely attract better suited friends for yourself.
Again, just something to keep in mind.
