Consider the question.

"What about all the things that are wrong with the Church?"

The fact that you could ask that question is an indication that you are seeing that there are things that are the Church and things that are not the Church.  You are seeing that there are things that have come into the Church that are not of the Church.  You can obviously see that these things don’t belong there. 

You are saying that you have some sense of the difference between right and wrong and the holy as opposed to the profane.

The church is called to become what is right in the Earth.  It is to be the salt of the earth, preserving that which has died and healing that which is infected.  It is called to be the light of the world.  Christ is to flow out through each member to believers and unbelievers alike.  The love, which God is, is to be alive in every member.  When the church becomes lukewarm, the unbeliever becomes confused and rightly asks, "What about all the things that are wrong with the Church?"

When a person becomes a member of the Church, they do not join.  There is no way to join.  They may join an organization, and that organization may call itself a church, but the real Church is something else.  You must be born in.  If you are born in, you are born as a baby.  Maturity will come if you walk with God.  Unfortunately, many Christians never mature because they never walk with God.  Immaturity in Christians is confusing to unbelievers and they rightly ask, "What about all the things that are wrong with the Church?"

That being said, unbelievers need to realize the following:

If you believe in right and wrong, then you do not believe in materialism.  Materialism has no basis for right or wrong.  Relativism is the belief that there is no right or wrong.  Post Modernism is really just a mental framework for Relativism.  An evolutionist, relativist, materialist, naturalist, agnostic, post-modernist, Unitarian, or Emergent has no basis for any talk about right, wrong, error, correctness, morals, values, or any such thing.  When they engage in talk about any of these subjects, implying that someone is doing something wrong, they are simply hypocrites.

If you are looking for a perfect church, it would be difficult to find such a thing.  The very act of joining a church is an admission of a sin and short-coming.  Every person who joins a Church is admitting a short-coming.

So, you are not going to find a perfect church until we come to an event that the Bible predicts, the manifestation of the sons of God.

If you are looking at the church in a way that is causing cynicism, the source of this judgmental attitude is not the Spirit of God.  It is important to seek God that your calling will be sure.  Look into the Word and see how to minister to your brother and sister in the church.  When God reveals the order of the Body of Christ and the reality of the life that is available through Christ, this moves you toward God and toward your brother and sister in Christ.  Satan only wants to destroy and take you away from Christ and His life.
