I found a couple of references where Waite uses "Catholic" (capitalized) in a context where it clearly doesn't refer to Catholicism.
One is from a footnote in The Secret Doctrine in Israel: "Neshamah is understanding in late Kabalism, the individual intellect communicated by the Catholic and Divine Intellect."
The other is from The Real History of the Rosicrucians: "His angelology is derived from the works of pseudo-Dionysius on the celestial hierarchies, and he teaches the doctrine of the pre-existence of human souls, which are derived from the vivifying emanation dwelling in the Anima Mundi, the world's spiritual vehicle, the catholic soul, which itself is inacted and preserved by the Catholic and Eternal Spirit, sent out from the fountain of life to inact and vivify all things."
These aren't statements of his own personal viewpoint, but they probably influenced him and it seems more likely than not that when he says "Catholic Mystic" he means the path of return to the Univesal Divinity. At least it makes more sense to me than "Catholicism" which he obviously rejected.
