Depending on the person, I would be SO tempted to say, "Why thank you! We're having a solstice ritual tonight, and I am thankful for your wish for a blessing on that. Peace!"

At least, though, it's better than what was on my cousin's answering machine for years: a wish for everyone to have a Jesus-filled day. They're IFB, and that's just P/C without the tongues. I guess saying "Spirit-filled" would have been too close to P/C for her comfort. I'm still a practicing Christian and just hearing her outgoing message made me gag. But I take the high road and don't say anything to her.... family peace and all that. Not that anyone puts much stock in what she has to say anyway.
