Sunday's Pretty Icons Lyrics

I think the title refers to objects in a church used in Sunday mass, such as a crucifix, wafers, etc. Like they're simply thought of as "pretty" because people don't take them seriously or think much about them once they leave church after the mass. I'm actually not a Christian so maybe someone else could offer a better explanation. However, I know that Stuart is very religious and often uses Christian references in his songs, like "Somebody asked me what hell was like" and "Every person that you despised is forgiven", which I assume refers to the notion that God forgives.

But can anyone explain the verse with the whisky? I have no idea what that's about.
