This creates stagnation in a congregation because the focus shifts from doing the work of the Lord to assessing the worker of the Lord. This does not mean that there is a time for a minister to be removed, but rather it means that the congregation needs to avoid this mindset. It is unhelpful and unproductive. The attention needs to be on Christ and the individual person. Deflecting responsibility rarely helps people to mature. One must own the situation instead of the easier mindset of blaming. Once a church shifts to the mindset of consuming ministers, you will rarely see positive and lasting growth. The church might love the next preacher, and there will be a increase of attention, but if the congregation sourer, or he leaves, the congregation will slide back in size.
You can see this happening in a congregation. When people leave assessing the quality of the sermon instead of the impact of the sermon the shift is taking place. "I did not like the illustration" is spoken, instead of "I need to focus on being compassionate this week." The ministers job is to facilitate spiritual growth, not appease the ever changing preferences of a membership. When people state "he does not visit enough" more than "I need to visit more often" you are seeing the consumeristic mindset unfold.
But with this said, preachers can do the same thing to congregations. A church is not a product. Too often ministers can treat congregations as a mirror. The ministers desires to mode the congregation into a likeness of his envisioning. He desires to find fulfillment in the congregation. If the congregation grows, it is a reflection on him, which provides a ego boast. A minister seeks to influence a church of his liking instead of allowing the people to be the people of God. Once again, product thinking is reigning. The preacher treats the church as a product to be consumed by his ego.
You see this transformation like this. The preacher makes changes or pushes for changes that the majority of the members oppose. The majority of members believe the Bible does not authorize women to be preaching on Sunday morning, but the preacher forces his position on the church. It is done because he feels that it is right. He demands the product suits his outlook. People leave, are hurt, and the congregation declines because he needed his way. Lord, give me a product that I would be proud of. He demands the church be a reflection of himself.
Preachers can be guilty of badgering a congregation because he needs it to fill himself. The church must grow because he needs it to make up for what he is lacking. The preacher turns his attention away from his work to blaming the church for the lack of progress. Instead of owning his behavior, it deflection on the church. If the church would be more evangelistic, then we would grow. There is nothing wrong for desiring growth, but if it is done to satisfy the preacher's ego, rarely will the growth last. You see the shift from edifying a congregation to perhaps shaming a congregation.
Congregations and ministers can fall into the "product" thinking trap. When we turn the church into a product, we become consumers, not Christians.
