Church a reflection of culture or culture a reflection of Church?

• I wrote the title as a question for which I have no answer. I have  concern.  The community of believers who describe themselves as sisters and brothers in Christ, acting like persons who have either misunderstood the teachings of the Christ or at least baffled by his life, confuse the world. Is it really because we succumb to the needs of the institution rather than staying true to the movement Jesus began? Some believe the church has to win. Some believe the church wins when it is strong and unchanging. The present church does not respond to the needs of people.  It continues to teach and "be" the same institution of the 3rd and 4th century, the 12th and 13th century.  Oppression, wars, suppression of thought are all a part of its history.  This is all forgivable when speaking of it as a past act but what have we learned? How should we have evolved? We teach that spiritual life is a continuing growth experience.  If that is so, why aren't we seeing that with the church? Does the church get a pass, because it is an institution? Why can we preach that people should be different, and not expect the church to grow and change? Is there something in the organization, culture, or belief systems that keep it from growing or changing? 
• I have no answers for any of these questions, but I do believe we are responsible for seeing that these questions are asked. As we seek to improve the institution let us consider how much better it might work if we work harder at being our best selves.  Imagine and work for the new YOU and the new "body" of Christ.
