I should think so. I never know what to do with specific language used vaguely. People hate being corrected, but absent correction the conversation descends into cross-talk and absurdity.
"Mystic" and "spiritual" seem to be the waffliest terms, followed at a few paces by "magic", "superstition", and "cult".
Sagan was all about verifiability, maybe even a bit of a logical positivist. In any case he really didn't distinguish between traditional religious woo and other forms of woo. He was particularly fond of trouncing astrology for example and went so far as to say we should not immediately discount things like prayer and Velikovskyism, but should instead submit them to scientific examination.
Sagan smoked some weed and opined at one point that Jesus must have been some type of an alien to have been able to perform impossible feats. Probably just the weed talking there.
He just didn't grant any particular form of woo any special status. It was all woo, all mystical mumbo jumbo when held up against scientific inquiry, observation and experiment.
