The Church is not free of societal corruption, because it is made up of people who will always fall short of the glory of God. There are many things I've picked up on in modern Christian society that just aren't quite biblical. They're not exactly justified means of expressing the Bible and the nature of God.
An example of these things is the whole "Jesus freak" thing. Jesus is God, not a rock maven, and I expect nothing less than for Him to be respected as Lord. It's disrespectful and demeaning to put Jesus on the same level as a pop-culture celebrity. Now, even if Jesus is Lord in your heart and mind, you should not portray Jesus as a hip-hop mogul as a way to convert people. And quite honestly, if you see Him on the same level as someone like Elvis, then you need to examine your values.
Another one is the "Hakuna Matata" Christianity, which is a belief that being a Christian is a free pass to an easy life. Weeeeeeeeell... If you are seeking to live like Christ, you better expect persecution. If you go into life expecting an easy ride, I guarantee, you will be sorely disappointed and hurt.
You see, those who reject Truth do so because they do not like the Truth --- it is inconvenient for them, and does not --- cannot --- fit into their humanistic ideals (or vice-versa, if it makes more sense). They reject Truth because it is anything but easy and comforting.
In fact, Jesus said, "Think not that I am come to send peace to earth: I came not to send peace, but a sword." (Matthew 10:34) The Christian way is anything but peaceful. If your Christian life is peaceful and serene, (waxing Blimeycowish) you're doing it wrong.
