Like Elixer, I am a long-time Rush fan also. Both my father and I have been for ages (he is a devout Catholic too)
I never heard that Alex and Geddy are atheist, but that is not to say they are, just never heard them admit that. I know Elixer did make a point about Neil being very open about his agnosticism/atheism, especially in later times. It shines especially throughout the past two albums such as Clockwork Angels and Snakes and Arrows. We bought every single album, but Clockwork Angels was the FIRST Rush album we did not buy ever. The songs are getting darker and more depressing. Neil’s agnosticism really has gotten to me and put a sour taste in my mouth.
Since Neil is the main lyricist for the band, you can almost see his spiritual journey and wandering, lost path he has taken over the past 30+ years. It ranges in some songs to pagan mysticism, to search for God and his Creation, to now with denial and doubt.
I have also read Ghost Rider, Neils book about how he motorcycled the circumference of North and South America after the death of both his only daughter, his wife, and even his dog in rapid succession. It has been a few years since I have read it, but throughout the book he is searching for God.
He comes so close sometimes! Like when he would stop in Catholic churches in Mexico to sit in adoration (even though he did not know that what he was doing), and he would comment on what a “beautiful peace” he would find just sitting in the pews in front of the tabernacle
Yet, he is so far away! Along with him indirectly questioning God about why all this sufferening and loss. Near the end of the book he actually consults a Tarot card reader.
All in all, I still listen to Rush, but gravitate to the albums such as Permanent Waves, Power Windows, Grace Under Pressure, Hold Your Fire, etc; which I believe are some of the most positive and inspirational of them all.
