Do we have any Latin-speaking jellies in the house that could help me translate?

This has been one of my favorite songs for years and I’ve always wondered what it meant. I love Latin and really should get around to learning it. Anyway, I sorta understand some of the words, but not enough! Can one of you devastatingly good-looking braniacs help a brother out?

Quod fuit est sicut quod erit
Et quod erit est sicut quod fuit
Quod fuit ad perpetranda
Miracula aeternitatis

Quod superius est sicut quod inferius
Ad perpetranda miracula

Quod inferius est sicut quod superius
Ad perpetranda miracula
