In the last several years, writers and academics have begun to seriously analyze what pop culture icons say through their worldviews. Books have explored the philosophy of The Matrix, Buffy the Vampire Slayer, and Seinfeld and the gospel according to Tony Soprano and The Simpsons.

Alistair Begg, pastor of Ohio's Parkside Church and the author of Made For His Pleasure (Moody), has been a longtime fan of The Beatles. He doesn't suggest the band had a solid theology or an admirable worldview. Instead, he feels the band is important to look at now because it asked a lot of pertinent question in its music—and too many of those questions went unanswered.

Why is it important to understand what The Beatles were saying during their era?

They were on the forefront of a generation's thinking. At the same time, they were able to articulate things and were given a voice. Without fully understanding it themselves, originally, they found themselves the mouthpiece of a generation. They were actually interpreting some of the angst, the hopes, and the fears of teenagers with mothers and fathers who didn't understand.

Did The Beatles simply reflect culture or did they shape it?

For good or for ill, they were shaping culture. That's true if you take the development of the music alone. Everything that they did pushed the frontiers out. This wasn't only true in terms of the way in which they were recording material or the way in which they were writing melody lines, but it was actually in the lyrical content as well. Think about what Elvis Presley was singing about, or about what Chuck Berry was doing. It was all about love and different things like that. The Beatles got into a whole new business the further they went.
